I have a Blackberry Curve 8310 and am trying to set up my BIS account. When I enter my PIN and IMEI # on the AT&T website, it says that my device is already registered with a different service provider and it tells me to re-register the device. What does this mean and how do I fix it?
Thanks in advance for any help!

Where did you get your BB?

I got it right from AT&T.

Call AT&T then.
