For the past 6 months or so my phone has been spontaneously turning off. It does it sometimes when I close the qwerty section, or when I hang up from a call, or I just go to used it and it's off. It was rooted on 2.3 (.1?) before, but I reformatted it and upgraded it to 2.3.3 because of this problem in hopes of stopping it. It didn't work =/ If anyone has any ideas please share. It's pretty annoying and I still have a little over a year with this phone. Although truth be told, other then this problem I love the phone.
