How to get a jailbroken iPhone out of a locked screen loop
On jailbroken iPhones where sbsettings is installed (nearly all of them) and the 'autolock' toggle is also installed, there is a chance of getting permanently stuck in a lock screen loop. When you slide to unlock the iPhone, it unlocks for a 10th of a second, then locks again.
The problem is that this unlock-lock loop stays through a restore. Try as you might: DFU mode, restarting, restoring from backup, etc., all will end with an iPhone in the same loop. This problem is caused by a bug in sbsettings' autolock toggle.
This is how I fixed mine when it happened to my phone last night... Now when I mean "fixed," I mean getting all my photos, SMS, calendars, contacts, app settings, call log, etc. back, but the phone is left unjailbroken. Since we have to do a restore through iTunes, the phone will be unjailbroken when finished. A re-jailbreak is necessary from the get-go.
