So I got my phone back today. I mailed it to them on April 28th. Did not take all that long. That was a relief.
Unfortunately it still does not work. Will not charge, no lights come on when connected by charger or USB cable. No sign of life at all.
The paperwork that came with it says:

:::::::::Here's what we did to fix it: Software Upgrade and Phone Reset.

It came with a different battery (did not send mine with the phone as instructed), and neither battery gets a response.

This is so lame. I find it hard to believe that anything was done at all.
