Hello all, im a new BB owner im new to this website i stumbled upon. im looking for anyone who can point me in the correct direction on where to begin. My current status is i have a Unlocked at&t BB curve 8310, my carrier is tmobile. i used to have the sidekick side with the $20 tmobile data plan.The sim is now in bb. i dont know if i have to cancel the data plan, downgrade or upgrade? what software do i need to add to get this to run great on tmobile? i dont mind researching it just that there is so much here kinda of confused as to were to begin. also since the 8310 is from at&t is it the same as the 8320 from tmobile??? Thanks to the community in advanced.
There was a guy with this similar problem, and after changing a few phone settings and calling T-Mobile to get the right plans and setting up the phone further, he got it all working. I think you should give that a try. Good luck!
