after updating my phone date today 2554BE iPhone 4

Never a dull moment with my apple products
I just updated to iOS 4.3.1 and realized on the date the year is 2554 with a BE at the end.
iCal reads year 2554 BE and all my imap emails cannot read because of this reason.
havent tried the other app yet but its freaking me out... might have to restore but if there is a quick fix that would help.
cheers!
