My Treo 650 went nuts this weekend. The keys would only work sporadically, and touchscreen navigation was painful. I couldn't reset it, because you need to use the directional pad to do a hard-reset on the device. I took it into the Verizon store to swap it out and they had none - none to order and none in stock. They sent me out to Troy (long ways away) to get a new one. Verizon customer support, as usual, was excellent. The guy worked hard to track the phone down and make sure I was taken care of. He spent 15 minutes on the phone calling stores to track one down for me. That's why Verizon is worth the extra money. I never hear any Sprint or Cingular customers raving about their customer service.
