I am about to purchase one of the above BBs. How do the web speeds compare between T-Mo, Cingular, and Nextel? I am in Chicago, and have decent coverage from any of the above services. Thoughts? I am assuming the email functionality of all of them is roughly the same? Thanks.

In DC, I find the nextel's to be somewhat quicker. Not quite 2x as fast, but still a little quicker than the other carriers. But nextel's out-of-DC coverage is pretty splotchy.

I'm finding web browsing on the 7100t (on TMo obviously) to be paintfully slow. I wasn't expecting much from GPRS as its roughly equivalent to dial-up, but I'm finding that the 7100t is much slower than my old Sony Ericsson P800 when it comes to web browsing. I'm not sure if its a hardware thing with the 7100t, or something to do with TMo's blackberry service (which would be my guess).

Not a deal breaker for me, as I don't rely on mobile web browsing much (occasional looking up directions or phone numbers), but it is somewhat dissapointing.

I'm loving the push email, however.
