I installed iOS4 on my 3G today and later realised that it wasn't prompting me for a passcode when waking it... so I went into settings, and turned on passcode lock which prompted me to enter my code.... twice. I put the same (or so I thought) code I've always used... I remember specifically watching the code go in... twice. At this point it's muscle memory so while I may have entered a digit wrong (twice?!?!) I've tried as many combinations as it would let me before going into 15 minute lock-down mode. Im completely screwed at the moment... because with my new fancy iOS4, I spent about an hour organizing 7 screens of apps into folders. I can restore the thing, but geez- there goes all my folder-ing. Can't I just plug it into iTunes to verify that I'm the owner? Or is restore the only option?
