I swear I searched for this first! Couldn't find anything, so if it's been answered, please direct me . . . or simply answer if you're so inclined.
I bought a Blackberry Tour from Sprint (set in CDMA of course) and shortly thereafter changed my carrier to ATT. So, I slipped in the SIM and set it to GSM. No problem getting BB email working, connecting to the network, etc. However, I only have an EDGE connection. What's the reason for this? How can I fix this??
