My understanding is that it's an FCC kind of thing. Since CDMA can't do voice+data, is order to get away with that with 4G, you'd need two radios running at the same time. With that comes an increase in the localized RF radiation exposure. So the FCC would have to OK that kind of operation.
[EVO 4G General] cloud858rk:
Well phones already have 2G, 3G, and Wi-Fi. I doubt Wimax is going to hurt anyone any more or any less.
[EVO 4G General] jmanley69:
2 companies? well, then you can probably afford a family plan and add another phone. Use one for your super important business calls and use the other for your mid-call surfing.
[EVO 4G General] johnsongrantr:
I was just reading back through this thread, I do want to mention something about 4g/wimax. Voip is totally a possibility with the extra bandwidth. When not using CDMA voice, data can still be used for voip calls and whatever needs you have.

I have a really good feeling google talk will incorporate true voip calling on android here really shortly with the introduction of wimax and other 4g networks. All unlimited and all for free. Well limited to an unlimited data plan.

No reason to doubt me on point 1 because it's true. Point 2 can be researched by goggling "google mobile strategy" they wrote a lengthy article explaining their roadmap a year or so ago that covered this whole thing in detail, I think most people have forgotten about it to be honest but it was all the buzz at the time... For like 5 min ;)
[EVO 4G General] joshuadb20:
No deal breaker for me

you could use both if you used wifi for internet
[EVO 4G General] chippillie:
No. I have not once needed to surf the web/data when on the phone.
[EVO 4G General] mountaindont:
there is something to be said about voice and data simultaneously
[EVO 4G General] pwabbit:
Same here. I am not saying it wouldn't be cool to have. It is just not a feature that I would use much.

Voice + 4G will work when the phone ships, however voice + 3G will not.
[EVO 4G General] MadLinx:
YES! several actually,

1. if you use a bluetooth, you can multi task while on a call.

2. needing to send or receive an email while on a call, for those wondering "why would you need to do that???" cause some of us actually work for a living & need to conduct different types of tasks while on a call.

3. GPS while on a call...do I really need to explain that one??

4. for some of us, our mobile is our only phone. if you happen to be on a long call (i.e. conference call that could last hrs) the idea of not being able to access any data can be a serious inconvenience.

5. needing to access information on the web while on a call. this can range to looking up info on where to have dinner to looking up car repair info while you are on the phone with wife, sister, mom etc.

6. being on hold for as many of us are from time to time it allows one to still be productive while waiting for what may feel like an eternity.

7. if it's possible...why not?
[EVO 4G General] johnsongrantr:
I've been thinking and I came up with a good reason, none of those apply to me however. Everything on that list can wait untill I'm off the phone afaiac, I can type the email or message if I absolutely have to while on the call and it can auto-send after the call is finished, that's the only one that really might ever apply to me.

btw I work for a living as well, my job just doesn't require I tap out an email while I'm on the phone with someone. I went and got a laptop with a real keyboard like a normal person.

Anyway, on to my reason, and you might agree it's the best reason of all ;) Tethering, you will have to disconnect every time you get a call... if you're on a laptop and a call comes in, if you answer it, goodbye connection. I have actually ran into this before, I guess I just got so used to it happening I must have forgotten. So I do agree, it would be very useful, especially in a phone that is being promoted as a phone + wifi hotspot.
[EVO 4G General] MadLinx:
Well being the "normal" person I am, it's not always practical to pull out then power on the get a connection then log in to a laptop for what should be a quick piece of information. And of course, what if you aren't within reach of your laptop.

the reason why devices like this are being created is to be able to do many of the tasks once relegated to traditional PCs.
[EVO 4G General] Dan330:
i personally think that voice+data is a big Plus. I will just be more convenient to access and to thing that.... DROID DOES!

Yes, we all on Sprint have worked around it... and are fine with out this ability. And don't really notice how often it comes up and would have been NICE to do when we... GPS, tether, Long ass calls, on long holds....

if you have not noticed this inconvenience....then you have not really USED your smartphone. :cool:

I want this phone and voice+data!!!!! :D
[EVO 4G General] keatre:
As I said before, Voice + 4G will work... Voice + 3G will NOT work... Voice + WiFi

may

work...
[EVO 4G General] Dan330:
yes, but that was not confirmed yet..

sprint said they are still testing it and has not released a confirmation.

HTC said the hardware and software can do it.. it was a service (sprint) issue.

Voice + Wifi was confirmed; Not Voice + 4G confirmed.

Voice + 3G confirmed it will NOT work (been the norm). I have read it can work, but was buggy and clog the network, so sprint will not support it.
[EVO 4G General] Aridon:
For me at least I really couldn't care less. Nice feature that I probably wouldn't use but once or twice a year. Compared to what I was paying at at&t sprint is a bargain with significantly better service. I got tired of not being able to use my 3g connection on my iphones and having to pay a premium on top of it.

So I accept the cdma limitation of no voice and data at the same time. In all honesty the average consumer probably doesn't care one way or another. If sprint gets it worked out with 4g great. Its not a big deal for me one way or another
[EVO 4G General] johnsongrantr:
3g to 1x seems pretty seamless conversion (evdo and 1x icons) and most of the time I don't really notice except it's a little slower, much like going from non roaming to roaming (triangle by signal icon) putting a seam where there wasn't one 4g to 3g with or without calls doesn't sound like a good idea.

I agree that your average person isn't going to give a **** either way, even if they did understand what was going on in the first place. It's the same type of person that gives you the deer in the headlights look when you mention anything technology related. Some people just have no freaking clue.

"wimax... is that like that twitter thing I saw on Oprah?"

EDIT: I have seen SO many non-technological people with android phones it's not even funny... in it's basic non-hacking form it's really a very easy to use phone.
[EVO 4G General] keatre:
I am telling you, 4G+Voice will work. Don't believe me, that's fine.. But I've spoken to enough people to trust that it will.

As to whether Sprint will allow it or not, not positive yet, as that's an administration decision, but the phone can support 4G + voice.
[EVO 4G General] mrmomoman:
Hurry up SPRINT! - The next BIG EVENT WWDC June 7th! Don't miss the boat again SPRINT!

The HTC incredible has shown that its got teeth. AT&T is resting on its IPHONE release in June so they don't care it seems to Android at this moment. They had the chance for two phones that would have been a good hit. The HTC Desire and the Samsung Galaxy S.

I hope they release before the IPHONE 4 does. If the new Iphone is the one what was shown on the Gizmode site with its 3.5 inch screen then no thanks. I don't need higher resolutions on a smaller screen. If its a 4" screen its a start.

I heard the EVO 4G might come with Android 2.2 Froyo? :)

Hurry Hurry Sprint! Time's a ticking!
[EVO 4G General] Antebios:
Yep, hurry up! I've got money that is burning a hole in my pocket. If I don't spend it soon on the EVO then I'm going to get another Android phone.

[EVO 4G General] tatnai:
I can think of one or two occasions in the last 1 year where I might have googled something while on the phone, but actually, not something I really miss not having with sprint.

also remember, looking at some posts, we DO get phone calls and text coming through when we are using data, it is not like they get bumped to voicemail or anything. so missing calls is not an issue. I use GPS while I'm driving around all the time, calls always come in just fine, and when I'm done, right back to my google nav like nothing happened.
[EVO 4G General] noah.labrousse:
does anyone know if this phone will work on the metro pcs network?:D
[EVO 4G General] realmrealm:
GPS?

Why are there so many posts about people not being able to use gps while on a call?

I do this almost every day. As long as you have put in your destination and it is directing you there both sprint navigation and google navigation will continue to work throughout a phone call.

I am constantly going from client to client, and the first thing I do when leaving a client is to start my navigation (I use google), and start driving, on the way I check voicemails, return calls, and even respond to texts while talking on the phone and having gps running.

I do this with my Hero now, and I have been able to do this with my last 2 blackberries also. Am I missing something?

**** AT&T. I'm going Sprint where I can get more than a 30kbps data connection.
[EVO 4G General] BrianDigital:

Voice + Data

I have to really really think on this one. I do 3 or more things often. Matter fact, im tetering, posting this, listening to Media Player and talking to my mother.

I do not work in sales, but I would imagine this would definately be a killer to them as they often multi-task.

And often I use GPS but either receive a call or have to call someone to tell them Im running late.
[EVO 4G General] Dorick:
This is a technological limitation of evdo which both Verizon and sprint are based on. Tmo. And Atnt use GSM which is able to handle voice + data. So no software update will enable this. Though wimax is able to handle data while evdo handles the voice. This though will be up to sprint whether they allow it or not
[EVO 4G General] zonyl:
+1

On 4G you can talk and use data at the same time! Many reviews confirm! Google is your friend.

On 3G voice calls incoming and outgoing will take priority (callers dont get a busy signal or bumped to voicemail immediately) and merely pauses the data connection for the duration of the voice call.
[EVO 4G General] gentlye:
I am shocked and awe'd that none of you have accurate data.

The limitation is either in the evo or htc framework.

Here are facts..

"1x" or "2g if you call it that cannot support data and voice at the same time

They are the same pipe, so to speak. That means data,sms, voice calls in a

Non-3g area won't fly

"3g" or "ev-do" data stream + voice or sms or gps will work.

4g....dunno I live in the woods..and don't have an htc or an evo.

Voice\sms\data and gps do work. I have never dropped a gps link

While catching a call.

Yes my phone is rooted\2.1...

No I cannot tether and receive voice...modem\hardware limited...

I know this for fact.sdx has a thread on forcing. Ev-do only and the

Thoery was proven then. For the record: I'm using a samsung moment.

Need more proof? I am going to make a call and hit submit reply as soon

As the call connects. So I either wasted all this typi

ng for nothing....or.....?
[EVO 4G General] gentlye:
I think what is more confusing is; verizon is using 850 + 1900

Bands...

Sprint is cdma 1900 only. Which is why droid is able to. Multitask

They are voicing the 850 band and using 1900 for data etc..

In theory the are the same as sprint. I'm told most of the verizon towers

Are actually owned by sprint...dunno

But it seems htc hardware and or framework might be the issue?

P.s.. I'm still on my call......lol
[EVO 4G General] Quiksmage:
on my touch pro 2, I will lose internet access upon getting a call or text message. My phone is swapped to x1. When I get a text message it is just a short interruption, but it is there. I'll be tethering and streaming video on my laptop and getting a call ends that rather quickly.
[EVO 4G General] Bp3dots:
Are you, by chance on Wi-fi? EVDO does not support voice and data without the help of a wifi connection for the data. This has been proven and demonstrated many a time.
[EVO 4G General] avalst:
I'd change it but i'm not sure how :)
[EVO 4G General] mikevillarroel:
Wow so far i can count like 5 peoples here in this thread that won't get the EVO because of its lack of use data + voice at the same time, that's sad, i guess they will be getting Iphones or Nexus ones uh?

Anyways should this be a must? i remember 5 or 6 years ago the use of data was a privilege, can people survive without this "multitask function" for 1 or 2 hours?.......i do, i run my own company too, y drive too, i use gps too, i send emails too, i have wife too, and i will get my EVO regardless of that TOO, i have a family plan with 3 phones on it, if i need data+voice so badly that i couldn't breath, for 9.99 i can add a new line and that's it.
[EVO 4G General] v2tech:
I have preordered EVO 4g from RS and going to try it for 30 days.

I am still holding my ATT iphone account until I make my final decision.

Point here is, I think not having simultaneous voice and data "may" be a deal breaker for me..will see..
[EVO 4G General] StepheGon:
You are mistaken. CDMA does not allow for EV-DO connectivity at the same time as a voice connection. It has nothing to do with the frequency.

CDMA handles voice data via circuit switching, in a similar fashion as landline phones, while data is packet routed in a fashion similar to TCPIP. The radio's in our handsets simply cannot function in both modes at the same time.
[EVO 4G General] misticjeff:
It can technically be done and is being explored by both Verizon and Sprint...

[EVO 4G General] splicitysplat:
Sorry I had to reply just because of your sig. I had the vogue until about two weeks ago when it gave up and died. Getting the EVO is going to be a HUGE step up for me. I have been without a phone ever since and can barely wait another week.

this is almost a non-issue for me... i'm on verizon now with a TP2 and never really needed it.

is it just me or do too many people seem to need to have GPS on 24/7... like really.. who really needs GPS going to work or the store? lol

GPS is a nice to have, but when to people REALLY need GPS? Maybe I am just blessed with a good sense of direction?
[EVO 4G General] KERKEDAGAIN:
yeahh..when we have root and 4g, downloading ROMs are a must for me. I dont like having to wait to get home to download an update, 'specially since i'm gonna have to transfer it to my phone anyway.

There's nothing I hate worse, though, than having my download paused because a call comes through..cuz it then takes forever to resume, and sometimes the download's canceled by the server. Simultaneous voice and data ('specially over 4g) will be superb in avoiding that frustration.
[EVO 4G General] KwestJones:
I'm shocked that most people are ok with it. I do use it alot, coming from AT&T. Its helped me win countless (not really countless) arguments with people on the phone, being able to google something right there and then. Like the iphone commercial I am able to surf the web while I am on hold. I've called the bank and been able to look at the transactions on my account while I was speaking to them from their website. I've found countless uses for it. I've been able to look up movie times and buy tickets to plan a date on the go. While I am in best buy, on the phone, I could look at Radio Shack's website for the price of the same item.

Just the fact that people are telling you you can't when other people can has to perturb you a little bit, EVEN if you don't really use it.

All that being said, I am still getting my EVO on June the 4th. I am in S. Jersey, near philly (GO FLYERS!!!!) , and I do believe 4G is live in my area so...

[G1 Android Development] Firerat:
excellent , thanks I'll take a look at this

I did try 2.6.33 a few weeks back, but the Old Network API got dropped in 2.6.31 and I never got round to having a proper look for a patch or patching myself.

at the moment I'm interested in the ksm, and I'm wondering if that will be of any benefit to us.

Not looked at the Dalvik Code, so no idea if it will run 'out of the box' yet.

If I understand it right we could get a reduction in memory usage, as each dvm will have pages of memory in common, the Kernel will essentially drop all the extra copies and share one with all the dvms.

But be honest I have no idea how large this effect will be, it might be negligible as we simple don't have all that many vms in comparison with the huge servers its aimed at.

[G1 Android Development] farmatito:
I've took a look at the KSM but dalvik or libdvm.so need to patched at the point where it creates a new instance of virtual machine but the code base is big and a cold dive in it isn't exactly easy. Somebody more used to the code should be able to do it.

There is also a memory compaction patch floating around, but maybe the overhead is to big.....

[G1 Android Development] alongenemylines:
I repacked this into superfast 1.2,

I saw overall boot time go down by a few seconds (boot time being from device off, to all widgets loaded, ready to actually use state), but didn't see really any gains over wg's kernel from there. Compcache was broken (as I expected it to be), but everything else was nice and fluid.

I wish I had time to kernel dev. I've built a few kernels for my laptops in the past, but never even looked into it for android. Life just doesn't have enough time.

i dont really understand much about linux kernels and stuff... always thought linux other than android sucked. far too complicated and never just... working... (some of you will probably hate me right now. :P)

anyway ive got a question.

compcache is not kernelspecivic, is it?

so i can use the compcache provided on the first page on any rom, am i right?

i will check out the new kernel later :)

thanks a lot for your effort.
[G1 Android Development] farmatito:
I think compcache is kernel specific so you need to use the one in modules.sqf.

If you want to extract it from modules.sqf you need the unsquashfs program:

unsquashfs modules.sqf

then pick the file called ramzswap.ko
