my 3g keeps switching to the little circle at random times i know its not my carrier because if i quickly go into airplane mode and out of it, my 3g comes back and stays what do i need to do about my jailbreak? completely restore? simply make sure it looks like a stock iPhone by disabling tweaks? if i need to completely restore, is there any way to save all my cydia stuff so i don't have to go through that hassle of redownloading everything? thanks!
