Problem is it just stops responding anywhere from every couple of days to a couple of times a day. It will just lock up and the only way to revive it is to hold down the power button until it soft resets.
I have done a hard reset and tried some tricks from forums, but no dice.
Are these likely to be still covered by a manufacturers warranty?
I don't think Grays are going to or are even obligated to care. I have emailed HTC as well, but hopefully someone here might know.
