Cell Phone not working!!!

If anyone is trying to call me, you'll have to call my home/office # (740)687-0508. My Google G1 has totally died--after many resurrections, this time it won't come back. After spending another hour on the phone with T-Mobile customer service--after many other calls and trips to their store, this time they're finally going to send a replacement. It's about time--since it's never worked like it was supposed to--and went into spasms of randomly calling people from my phone book, turning the ringer off, buttons not working and having to use the "back" button to switch functions, e-mail not able to be checked, not receiving e-mails for days--and lots more fun, weird inconveniences. Hopefully, the new one will be as it should be--of course at this point it would be nice to have a phone that would at least function as a phone.
