I finally made the switch back to a BlackBerry (7290). It was a tough decision to buy now, as the 8700 is coming out pretty soon and looks really nice. However, the price was right – free. Overall I’m pretty happy with the customer service I’ve received from T-Mobile although I’ve only spoken with them a few times. One word of caution – the blackberry data plans do not include SMS. And since their IM client uses SMS, you could rack up some serious charges without realizing it. I spent $0.55 in 1 minute of testing the service before I realized I was paying $0.05 per incoming/outgoing message. T-Mobile could definitely be more explicit when explaining these charges.
