First, here's my T-mobile experience. Second, was wondering if anyone has AT&T experience with their N900.

T-Mobile experience: Crappy reception. I have been from Connecticut to Massachusettes to Vermont and the reception leaves much to be desired. In Connecticut in the Hartford area, I have zero signal except literally in a corner of the upstairs bedroom. In Vermont there was zero signal period for most of my drive when I went snowboarding, and the moment I opened up a browser I'd get a warning that I'm roaming. In California up and down the coast I've had frequent lack of signal. Driving down the coast from San Francisco to Los Angeles phone calls were dropped every few minutes (I'm talking every 1-3 minutes, not 10-15 minutes). Throughout Los Angeles I frequently had up to 20-second stretches of not hearing anything from the other side (the person I'm on the phone with) before they pop back in for a few moments, and then breaks up again. I mean in the heart of Los Angeles, it doesn't get more metropolitan or more "major city" than that. In most of these locales I've mentioned, my signal reception fluctuates from zero bars to four bars, and from 3.5G to 2G.

It has been difficult on the East Coast but I didn't use the phone all that much while working on my projects there. When I was on vacation and able to chat with friends more, that's when it hit home hard. And then it was so horrible in California (when I expected even T-Mo should be more than adequate in Los Angeles) that I kind of regret leaving Verizon. I left them due to lack of phone selection. But a nice phone on a network that doesn't cut it makes no sense either.

AT&T: Has anyone used the N900 on AT&T's network? Any better with reception and call clarity? I've read that the N900 can't get onto AT&T's 3G network, well how significant of a difference is their 2G compared to T-Mo's 3G? After all, at home and at work there is likely WiFi so you don't need to use the carrier's cell phone signal.

Other thoughts: Has anyone had first-hand experience with any "cell phone signal booster" devices?

Thanks!
