Hi, My Ipad is password protected. 4 digits. After upgrading today to IOS6, it requests a password but informs me my password is incorrect. NO, I have not forgotten my password - i use it 20 times a day! The Ipad keeps locking up after I try - it now locks up for 15 minutes and I am afraid I am running out of attempts. If there is no default 4 digit password and if it does not recognize my password - what do I do???????? your help is GREATLY appreciated.
