The Apple iPhone has a Safe Mode?
The Apple iPhone Safe Mode, it’s a funny looking screen, and well we’d expect a Microsoft mobile phone to pull such stunts like this from time to time, but honestly from an Apple iPhone?
Do you remember TUAW’s Erica Sadin after that AT&T Pay-As-You-Go Apple iPhone trick; she managed to find an Apple iPhone in Safe Mode.
So here is just how you can get yourself one too, just set your jailbroken Apple iPhone to “fast respring” simply by turning on one of the SpringBoard relaunching options via BossTool, and then you have to hope the SpringBoard crashes in order to gain Safe Mode, and there you have it.
