My Ally updated Thursday with no issues. I have observed a noticeable increase in responsiveness. Noticeable! No app issues. I did uninstall some new apps it placed on my phone like Skype. Battery life seems to be as good or better than prior to the update. I'm a light user. A couple of calls per day, some internet (Dolphin HD) and some texting. I recharge it every other day when battery level gets down to about 30%. I use ADW.Launcher, Juice Defender, no app killer, a couple of low overhead widgets, Chomps SMS, Pandora, and not much else other than a few shortcuts. I do have a widget for airplane mode. I turn it on once a day then reboot and turn it back on. Not much science here.
