Yesterday an official ICS (Ice Cream Sandwich, Android 4.0) build for AT&T’s Galaxy S2, (non-LTE) was leaked to the public. The build was quickly ready for an Odin flash thanks to the people at RootzWiki. I was able to download and install Samsung Kies (for the Windows drivers) in moments. Then I downloaded Odin from RootzWiki and began pushing it out to my GS2. I have to say the process, as always, was pretty straight forward. I’ll run through the process and possible issues in a moment. Once completed the process I had my GS2 running the sweet ICS we’ve all looked forward too! The OS does have TouchWiz running on top; however it is so clean that as in previous version it blends very well. I did run a few speed tests following my flash to ICS and was averaging around 7000kbps down and 1000kbps up. Prior to the upgrade I had averaged around 3500kbps down. I think that shows a dramatic increase in speeds. So far the only issue I have found is with the alarm clock and the ability to schedule it for different days. I’m assuming this will be fixed before the its officially released. I was able to fix it by just installing a separate alarm clock app. I don’t have very much more input yet as I haven’t messed with it much more. I look forward to playing with it a lot more and playing with all the awesome features that the latest Android version has to offer. – Greg

If you run into any issues while this is running, errors, or it just hangs for longer than 30 minutes. Unplug the phone, close Odin, plug the phone back in, run Odin and click “start” again.
Beginning tomorrow AT&T’s Galaxy S II Skyrocket will begin receiving an OTA update. This update is not Ice Cream Sandwich, Android 4.0. This is merely a maintenance update that will that will add several new enhancements. These enhancements include:
• Improved performance from several Qualcomm patches and other refinements
• User Interface updates such as the new screen unlock swipe
• The ability to ‘reply all’ in MMS messages
• Exchange ActiveSync wipe to remove all content from the device and microSD card
• Improved battery indicator icon accuracy
This update will bring the Skyrocket to Kernel version 126.96.36.199, Build number GINGERBREAD.UCLA3. So, those looking for the ICS update you wait will continue. –Greg
