How do I set up a wake up alarm to turn IPhone4 on, from off?

[kaveh79]

When I set up an alarm, It does works just in case the iPhone is ON. I mean, when the iPhone4 is turned off, alarm does not work at it all, till turn it on. I'm late everyday because of that, please help me!

Hey kaveh79,

The alarm still works if:

• The silence button is on.
• The phone is in flight mode.
• The phone is just in standby mode (just top power button)

If the iPhone is actually powered down ("Slide to Power Off") then, the alarm will not work.
