is there any alarm app that will be activated even when iphone is turn off?

My Blackberry allows auto on off at user defined time. Or even if phone is off it will sound when alarm is activated.

so do u guys switch off your phone every night? i need something that can wake me up every morning w/o hv to keep the phone on. i know we can do this by setting airplane mode, but it troublesome to repeat everyday, and hence sometimes will forget to put airplane mode off.

yeah. it doesn't. so is there any alarm app that will do the job?
