Its a known problem, apparently. How can you afford going thru 4 of them, i know i know its warranty not resale, but still theres a deductible...
There's a deductible for insurance replacements, but not for warranty replacements.
Luckily, I haven't had any major problems so far, and I absolutely love the form factor of the device. I thought I'd be bored with it pretty quickly as well coming from a Droid X, but that hasn't been the case at all. I see this phone sticking with me for quite a bit longer than most.
