Is there a way I can set my iphone to call someone at a certain time?

My friend wants me to call and wake her up at 5am tomorrow but tomorrow is a day that I actually get to sleep in and I would like to help her in anyway I can (I'm madly in love with her) but I also want to sleep as much as possible. So is there a way that I can set my iphone to call her with a recorded message at 5am?

No. Her phone can have an alarm.

Tell her to set a fu<king alarm, or set yours and call her… Then go back to bed… How hard is that?

Sorry, iphones can't do that without jailbreaking. You can actually go to wakerupper.com and do a auto call there. It will send a call at a certain date and time to a phone number. Hope this helps. BTw wakerupper.com is free
