I can't seem to find my answer anywhere, so... Does EVERYTHING work fine? Do all the apps, winterboard, SBS settings, gpsphone, NES emulator work fine? Do I need ANYTHING additional for these things to work? Or can I just jailbreak and sync? I really don't want to update and then find out that something or the other is not working. Is everything compatible on 2.2.1 compatible with 3.0?? Also is the battery life with 3.0 better? Thanks.
