I had unlocked several iphones. Few of them are having call receving problem, its showing full signal network. But when somebody calls on your iphone its telling you that the mobile is switched off. I did restore so many times but no hope. After few days the problem continues. So anybody facing any problem like that. Let me know

I have the same problem! Any way of solving it?

Did you do a clean restore and set up as a new phone or did you upgrade or restore from a backup made in 2.xx?

I did a fullrestore. Sometimes I receive calls other times no...it's very very strange. The problem I had with previous ultrasn0w was the NO SIM issue with this SIM card so I always had to swap cards to get this one to work. Now with 0.9 I no longer have the NO SIM problem but sometimes can't receive calls even with full network.... Very Very strange!


Anyone?

From MuscleNerd Twitter:
For anyone still having issues with ultrasn0w, here are some ultratips: Dev-Team Blog - Ultratips

None of those tips refers to not receiving calls after ultrasn0w 0.9 ......I think that this problem has to do with the SIM itself as this one always gave me NO SIM and I had always to SWAP SIMs to make it work. I'm going to ask for a new SIM to the operator....just to make sure!

i read in some blog that if SIM voltage if 5 volts then some issue if its 3volts then there are chances you can get this problem solved.

Sounds very strange … but try reset network settings and turn off 3G
