Is it safe or should I disregard these until I upgrade to/ jailbreak 4.2? I remember after updating some apps on my old 3G(j/b 3.12) to 3.13 my phone started crashing alot and after a few reboots wouldn't come back up fully, forcing me to restore/ update to Apples latest iPhone software/ killing my jailbreak...? Could this happen again? I'd rather stay away from iTunes for awhile than go through that again... From what I've read 4.2 doesn't sound like a great leap from 4.1 on an iP4... Opinions? I usually sync daily for podcast for my commute to work. Even w/o phone software, there's reminders for app updates...
