One of my friends got a 4s last week, but she has problems with the WIFI. Every time she wants to make a FaceTime call it freezes within ten seconds and her WIFI breaks down. She has Internet TV for instance which breaks down when FaceTime freezes. There have been NO problems with iPad. Any suggestions?

What's the difference between a Normal restore and DFU Restore? And how do you make a DFU Restore?

Google is your friend for those answers.

Anyway:

DFU stands for 'Device Firmware Update'. It is a special state where your phone's only active function is to update its software. You can achieve this state by holding both the home and lock buttons while connected to your computer and iTunes open until the screen goes black, then releasing the lock button and remain holding the home button. A message will pop up in iTunes after about ten seconds saying "iTunes has detected an iPhone that needs to be restored". Click 'OK' and then select the restore button in iTunes and let iTunes do its thing.

You iPhone will then be DFU restored as new to the latest firmware, which will be 5.0.1 as of today.
