T42G 29.73.0.45 latest Firmware, still reboots randomly

[opt2bout]

I did tag a reply to another post but thought I would post this separately to get support on this issue.

I have a new T42G, factory defaults. v72 firmware out of the box. I installed the phone and set up a single account. Before the account even registered, the phone rebooted.

I removed the Yealkink handset adapter and tried again. I got the phone to configure with the Voip provider but the phone constantly reboots. There doesn't appear to be any pattern to this...I can be in a call, or it can just be sitting there doing nothing.

During testing with the service provider I unregistered the phone and set up dummy accounts for testing. It still reboots.

I have upgraded the firmware to the latest available to me (29.73.0.45) and it still is rebooting.

Other than returning the phone, do I have any options?

Thanks
