My gf just upgraded to a 8700g since she was having way tooo many issues with her mda..she was told by customer support that she can use the phone and not have to add the blackberry data plan..upon receiving the phone she is only able to make one call and then she can't use the phone at all, she can't send sms or make or receive calls. seems the only way we got to the phone to work was by adding the blackberry data plan..before adding the plan she would have the edge in lowercase and it would right away go away after making the 1st call..then after adding the plan she was able to use all functions of the phone? has tmobile made some changes were your forced to add the blackberry plan in order to just use the phone to make and send sms?
