Hello. Added a passcode/password to my phone a few hours ago (chose a 4 digit number). Prompted me to re-enter it. I did. My phone is now locked, but when I enter the password, it says it in incorrect. I have tired it multiple times and I'm positive it's the same code I entered when creating it. Help? What do I do now? (I have had the phone over 2 years and never use the password feature before).
