So your using the stock rom and not rooted and using a custom rom? I am using a custom 2.3.3 rom and when holding the power button i get multiple options, power off, hibernate, restart, hot reboot and so on. Maybe that's the way sprint has it set up i don't know since i don't have the stock rom, but i wouldn't think so, maybe pull your battery and restart the phone and then if it does it again factory reset it and if that doesn't work either call sprint and tell them or root the phone and run one of the many great GB roms that are out.
