iPhone 3GS locked up on it's own - maybe becasue of AT&T update?

[cellulartalk]

My Iphone 3gs since April has been unlocked after going to unlocket.co.nz and now suddently I get this can not connect message so I can not get email but do get text and phone calls. I have straight talk and an AT&T Sim so I went to the Apple store for wifi tried to use that same website...
