I unlocked my 7100t and got a Cingular SIM which is provisioned for full Blackberry Internet Access. I want to use Cingular's blackberry website
http://www.cingular.com/blackberrystart. However, when I enter my Pin and IMEI, I get an error saying I already exist in the system. I have contacted T-Mobile and had them shut off my blackberry access but apparently, I still exist somewhere in the system. How do I get this corrected? T-Mobile refuses to help.
Thanks
