my phone keeps puk locking itself, powering off/on, and resetting itself randomly. have tried over 15 sim cards, 4 new phones and gmail accounts. called verizon multiple times and htc twice. htc won't help they say it is verizons problem. verizon claims that they have never seen this issue before. they want to either keep sending me the same phone that keeps locking up and have me continue paying for a defective phone i can't use. or the want to replace my phone with a certified like new verizon phone that is two years old and have me keep paying the premium price for the htc. i need to figure this out because i have been paying for a phone that can't be used for two months. i am really disappointed that i am paying for a phone that is defective and verizon agnowledges that but won't fix the problem with a device like the htc. any help would be nice. Thanks!
