Thanks for the help everyone, but no luck. When I called AT&T they first insisted that it was impossible for me to use the BB Storm on AT&T, then when I finally convinced them that I did infact use it on their network, they said that I still had my old BlackBerry Bold on my account.
The CSR told me that he wasn't able to do anything with the BlackBerry stuff, only that he could change the IMEI of the phone on my account.
I have been working with the guy to whom I told my phone, we changed the APN settings, did the HRT> Register Device option, and the registration message won't come through. Could that be the problem? He isn't about to register the device through the menu.
What could be going wrong that he couldn't make the phone register on the network? I had no problems doing this.
Thanks in advance!
