hello.
i just realized my phone is not turning on, when i hit the sleep button it brings up the sprint and windows boot screens, then turns back off, i try the softreset and does the same. i can not get this to turn back on, i tried pulling the memory card and so on with no luck, any ideas guys or is it time for a trip to sprint and use the 6 buck a month plan. which i hope not...... thanks in advance kenny
