I noticed this today,my status bar disappears for no reason and comes back if I lock the phone or just appears again randomly. Has anyone else had this problem? I also noticed that the phone was not getting any signal. The T-Mobile wording and bars were there, but I could not make calls or send texts. I had to re-insert my sim card to get it to work. I have my iPhone (3g, V.3.0) unlocked with ultrasn0w. I downloaded about 12 apps (from the App Store) yesterday because they were all wiped out when I did the ultrasn0w unlock (I was on 2.2.1 yellowsn0w), so I'm not sure if it's because of this. UPDATE: For some reason, "springboard crashed", so the phone was in Safe Mode. Anyone encounter this issue? Should I do a DFU restore? I don' know how to back up apps and pics. It's a hassle doing it all again. Appreciate any help.
