IPhone 4 (Sprint) Ghost line.

[Apple.of.my.I]

Ok so here is what happened. My wife's niece jail broke her iPhone 4. One of her friends did the jailbreak for her so she had no idea what kind of jailbreak she had or what version. Anyway she can no longer make any calls or messages. She called Sprint and they told her she has phone service and that she has to send the phone to Apple. Se still ant make any calls. They told her it was some kin of virus related to a "ghost line". Sound weird. Has anybody encountered something like this? Any suggestions? She tried to restore the phone via iTunes but no luck.

Put the iPhone in DFU mode then restore via iTunes.

Method 1)

Attach the phone to the pc
Turn the phone off
Hold power and home together for *exactly* 10 seconds
Release power but keep holding home until the pc beeps as a USB device is recognized.
At no point will the display come on. Now your restore should work.
Having problems? Try adjusting the 10 seconds to be slightly less like 9 seconds, then 8, then 7. It’s a tricky timing but you will eventually get it.

Method 2)

Hook up the phone powered on to the PC
Now hold home / power until the phone turns off and keep holding for 10 seconds. If the phone ever turns on during this phase,start over and hold for less time.
Now release power and continue holding home until the PC recognizes the phone.
I don’t like this method as much because there are “rumors” that it may cause some 1604 errors in the restore. I am not convinced of that though.
Method 3)

Attach the phone to the pc
Turn the phone off
Press and hold power. Keep holding power. As soon as you see display on the screen of any sort press and hold home.
Hold power and home together for *exactly* 10 seconds
Release power but keep holding home until the pc beeps as a USB device is recognized.
At no point will the display come on. Now your restore should work.

Make sure to back up the phone before doing this (if you haven't done it).
