Pleased you were able to get some benefit from this site! Thank you for the response! I remember your earlier posts...
The techs at the store are trained to make money for their employer. you would be surprised at the large number of people who blindly go into these cell stores of any carrier and spend the money on something they could have fixed on their own by a simple internet search.
These phones are pretty solidly built and yes the weakest link is indeed the usb port, but with so many apps on the market, things can happen and a glitch can cause your phone to do things it normally doesn't. They cant really be explained and once the phone is back up and running, the issue usually does not come back.
that was long winded. glad you are back in bizz star, and I hope Legal can figure out whats going on with his/her device as well.
