[AT&T Samsung Galaxy S II Skyrocket SGH-I727] scott14719:
Ok, here is an update to my earlier post.

I am now back on GB. ICS is great, and for me there were not any noticeable bugs with the install. It is very responsive, and has some neat (useful for some) additions from GB. However, I decided to go back to GB (Alien 6) for the following reasons:

1. Let me start by saying that issue 1 is more than likely caused by issue 2. The first issue is battery life. CPU Spy reports that the phone is "deep sleeping" like it is supposed to and the "display" settings are set the same as I had with Alien 6. I truely believe the The ICS leaked ROM and Kernel does handle the battery well. I also think that some of the people that do not experience issue 2 may find the battery life to be equal or better than what they had on GB. However, that brings me to issue 2.

2. Poor connectivity. I equate this ICS baseband to the performance of the earlier GB basebands (before UCLA3). If you are constantly in an area with strong signals, you may not have a problem with this at all. However, I work in an area of weak signal and the ICS basebands (and pre-UCLA3 basebands) suck when it comes to these areas. Let me add, I have not tested the actual data speeds, but for me it wasn't the issue anway. And here is why I think this issue is mostly causing issue 1. Any phone that struggles to get a signal, has a weak signal, or loses signal (constantly trying to connect to a network) will always use the battery faster. It will drain the battery fast. It doesnt matter if its wifi (I have read of others reporting weak wifi connections with the ICS baseband) or if it LTE, 4G, edge, whatever. So until a better baseband (modem) is released for ICS, this will always be a problem for me.

3. Contacts derped! Not a huge issue but more of a pain in the ass. Having the "full" contacts available via dialer is nice. The ICS dialer provided half-assed contacts via the menu button on the bottom. I'm sure this will be corrected with an ASOP dialer or when the DEVS get ahold of it, but until then it sucks.

Other than that, it was OK. Face unlock and all the stuff like that is more of a novalty really, but still is nice. I'm guessing people that use their phones alot to game or for CPU intensive stuff may get a boost from ICS, but for regular stuff...its GB and Alien 6 for me.

For those wondering how I got back to GB:

1. I used the I727 firmware from SamMobile. It worked great and restored the phone without tripping the counter. The strange part is (unexpected) all of my user data was ported over including apps, accounts, settings, etc. Of course, It was not rooted (didn't need to be) so some of the programs would not wotk with "SuperUser", but everything else worked fine. I completely expected a complete fresh start because the firmware was flashed through ODIN, but I guess they built the ability into the TAR to port user info and data over?

2. I installed CWM via ODIN. It worked, but gave me a couple of error messages and app FCs upon reboot? The phone worked fine after it finished booting though, so I'm not sure what it was all about. But like I said, everything still worked fine. Maybe it was once again because it wasn't rooted?

3. I flashed the UCLA3 baseband via CWM.

4. Installed the nandroid I made right before I Odin'd the ICS leak.

All is well back on GB, ALien 6, and UCLA3 baseband (knock on wood).
