I just sent a 770 in for repair of the WSOD. Unit was purchased in Oct. of '06. Made a copy of the receipt and sent it in for repair. I got a letter in the mail stating "We have received your phone for repair and determined that your phone has an expired warranty. A copy of a valid proof of purchase (receipt) dated within one year may be submitted to place the unit in warranty. A valid proof of purchase must include the the serial # (ESN/IMEI). seller's name, address, and phone number." WTF. Compusa or anywhere for that matter doesn't put the serial number on a receipt. I guess it doesn't help that the COMPUSA that I purchased it from has since shut down. I'm calling 1st thing Monday morning. I can't believe this. Oh and the price to repair.........$175 + $8 shipping. Anybody else run into this?
