try reloading the rom. maybe it's a glitch.
it would't be the first time people have had problems solved with a wipe and reload.
and if your rooted. that's the first thing sprint is going to do is restore phone to stock. so might as well save yourself the hassle and try it at home first.
Can the wipe and reload be done without the phone being connected to the pc? Remember, this phone does not connect as disk drive so I cant move things from pc to phone.
btw, no my phone is not rooted
