The date on mine is 3-3-08. As I said in another post I woke up last week and my Q was dead. After I charged it for 3 hrs and would not turn on I took it to Sprint. They said it was a dead batt and replaced my charger. Today the phone has totally dumped all my settings (registy included) when I power it down. No matter what I change it comes back up default settings on a reboot. So far it has not "locked up" on me but it is still as useless.
