Changed to T-Mobile two weeks ago and got these phones for self, wife, and daughter. Wife and daughter, severe critics, gave thumbs-up to phones and provider. T-Mobile beats the heck out of AT&T coveragewise for us where we live/work/play (Los Gatos, Cupertino, San Jose, CA). Note that I got the phones for FREE (after rebate) by waving the first page of the Amazon listing for the V300 under the T-Mobile saleman's nose. Saved $750!
