Sorry to hear your Cingular experiences were difficult; and we tried to help;

Rumors say that T-Mobile is going to announce the 8700 sometime in April. Keep tuned. In the meantime, you may just have to make do with a Sidekick. The Treo is also a nice unit in many ways, but it is a totally different feel than a Sidekick or BlackBerry. Personally, as a heavy duty chat device, the Sidekick 2 appears much better, while the Treo has much more email software options available.

Unless your main usage is just a phone, I would not suggest the 7100, since that model is much slower than a Sidekick and the SureType is a frustrating transition for someone already used to Sidekick QWERTY keyboards. Sidekick users found it easier to transition to a Treo or a full QWERTY BlackBerry.
