I'm travelling quite often by plane, and I figured out that my iPhone have a problem: I can switch from normal to Airplane Mode, but I can't switch back to normal mode. I tried several times, but always with same result; to switch back I have to power off and restart the iPhone!
Anyone with the same problem?
P.S. I bought my iPhone unlocked, then I don't know in which way was unlocked.
I have the same problem with switching back to normal mode after airplane mode on my iPhone. I cannot search for GSM carrier. I bought my iPhone unlocked. Please tell me how to solve this problem.
