Cingular Blackberry Curve Help

Please help me figure out what's wrong with my Curve. Phone has worked great up until yesterday. Now, Emails (pushed from Gmail) and any Facebook (bleh) updates do not go through. SMS, calls, voicemail, etc. all work fine. Browser works, Google Maps works, everything but email.

I've tried setting up the email account from scratch again. The dude at the Cingular store had no clue what could be causing it. He told me to call Cingular tomorrow and try to get a replacement since it's still under warranty.

I read something about updating service books, but I'm not sure what that means or what it does.

Any help, as always, is greatly appreciated.

go into the email setup icon on your phone and log into the blackberry account page, and click resend service books. Not sure if AT&T have that page. They should, with Sprint and nextel it's *carrier*.blackberry.com

That did it!

Thanks
