I am a long time Blackberry user (7230) who is finally completely fed up with the dark ugly screen so I am looking to get a new one. Although I am a Tmobile customer I am willing to switch to Cingular if the 8700 series is worth it. Though I am not sure their plans are international and I must have international as I travel a great deal).
Anyway, I am looking for advice. What Blackberry should I get? Bright screen, light in weight and long battery life are most important to me. Though I wouldn't mind be able to play MP3 and I definitely want one of the ones that you can use as a modem or your laptop.
