[Nexus 7 3G Android Development] kRt_uK:
BEFORE YOU POST HERE - Keep in mind this is now a DEV thread and only those with a glimpse of DEV knowledge should be posting.

There is other thread with the same subject open to everybody discuss it.

Please, this thread isn't related to VOIP, SIP calls or Tethering and

It's only to 3G version of Nexus 7.

What do you think is the possibility of us getting this function guys, even if its not officially supported.

I've seen it built in on the 7" samsung galaxy tab 2.

At the moment we know:

1- The chipset Intel (Infineon) XMM6260 is built-in on Nexus 7 3G (the same chipset is in that rather long list of phones). It means no hardware limitations.

it also the same controller is in the following devices

- Lava XOLO X900 [Phone]

- Lenovo K800 [Tablet/Pad]

- LG-P920 (LG ?) [Phone]

- LG-P925 (LG Optimus 3D?) [Phone]

- Huawei E369 (3G Hi-Universe) [USB 3G Modem]

- Huawei MU733/MU739 [PC/CE Module]

- Samsung Galaxy Nexus (I9200) [Phone]

2- SMS texting works perfectely with the native mms.apk but MMS messages crash the app (missed mms APN + framework parameters?)

3- Modified framework-res.apk (by modifying bools.xml entry to name="config_voice_capable">true) shows up the native dialer (phone.apk) on the UI

4- When placing calls trough the native dialer (phone.apk) with Skype app installed, it shows up a white menu asking "Do you want to complete this action using..." the options are "Mobile data" (w/ phone.apk blue icon) or "Skype" (w/ skype icon) and "Always" or "Just Once" (perhaps there is missing a "Phone" profile (or APN) as an option too)

5- If Skype is chosen, the call is complete and everything goes well, but if "Mobile data" is chosen, we get a single sound (bip) and the call is not complete.

6- Changing the DPI to 320 in build.prop file allow us to add a SIP account (SIP calls using native dialer is now possible), DPI could be restored after SIP account settings done.

UPDATE 5th Dec 2012 by Synman

ok, I hacked NetworkPolicyManager and am no longer crashing. Network time appears to be non-functional for the time-being. Network status is a little wonky too ... even though I have a good network signal the network icon never switches from gray to blue.

MMS send/receive is fully functional (with the exception of screwed up timestamps)
