I'm in Philly with this and I have 3.5G; speeds are decent when I have 4-5 bars but the connection is really spotty. If I go into an elevator it drops and I have to manually reconnect it when I get back out.

Idk if this a T-Mobile problem or just an N900 problem... The N900 really sucks with internet; one would think that with a mobile computer based device internet connectivity would be good but meh.
