Passcode problem

[damover]

I downloaded some Apps from my computer and sync into my iPhone 4, then after the syncing my PASSCODE can't work anymore. If I enter it, it say wrong passcode but am sure that it's the right one. Pls can one give me a way out to unlock my iPhone. Am in china presently. Thanks all

Take it to an apple store and ask them to reset it to the factory settings. You will need to download your apps and music again. Also see if the people at Genius Bar can help
