Hey Lan,

Considering it states "Restore Needed" have you attempetd resetting the phone to factory settings through Itunes? That way you can find out if it's a software or hardware problem.

Also, when did this start happening? Was it after a drop? After spilling water on it? Or does it seem completely random?

My daughter has my old iPhone 4 and it started doing this. I restored. It did the same thing after a few minutes..... I restored again, and again.....No difference. So I searched the internet and tried everything possible. (New SIM, turning off the PIN code, turning off 3G, Restoring in various modes.....etc, etc)

I was about to throw it against the wall................

"Wait.....", I thought to myself..... Sometimes it doesn't register that I take the SIM out, and sometimes it didn't register when I put it in, or it took longer than normal to notice.

"Maybe the contacts are corroded or covered in dust?". I sprayed WD40 onto to SIM and inserted it. Voila!

2 days and it hasn't lost signal. Hasn't asked me to restore. Runs perfectly, again.

I can only think that the contacts were dirty. No idea how because it's in a case, and the SIM hasn't been out...... Almost 2 weeks of stress and head scratching for a quick squirt of WD40.
