My G3 is dead.

AT&T didn't offer to replace it for you? Sprint has always repaired or replaced non-working phones for me. Frequently at no charge even when out of warranty, always at no charge when in warranty.

AT&T replaced it. The replacement arrived in the mail today, and I'll be mailing back the dead phone as per their warranty policy.
 
Wow. A positive AT&T story. Nice to hear for a change. Glad it worked out for you. I think a lot of phones have a hard time when battery drops into single digits.. iPhones especially. At least we can carry a charged spare for the G3. Better yet, get a 10,000 mAh auxiliary battery pack and keep it nearby in your car or travel bag.
