I upgraded to 2.0 and all was working fine all day. Downloaded a bunch of apps, still good. Went out for a couple of hours, downloaded 2 more apps, went smoothly. Came home, plugged it into my computer to sync with iTunes, frozen. Reboot the phone and now it's stuck at the Apple logo. Anytime I plug it in it locks up iTunes. I suppose the timing couldn't be better, right? This just makes me fear for the 3g's stability. edit: there it goes, came back on after letting it hang for maybe 4 minutes. I'm not liking that.
