i Found the Basic problem of iPhone 4S Signal bar Many are having these errors :
- Sim Failur
- No Service
- Invalid Sim ( After " Sim Failure " appear )
- One bar signal and sometime none bar ( ----- )
For iPhone Factory Locked and Unlocked
The basic problem when you get these error jump to Settings ==> Phone ==> Show my caller ID ( will appear off ) when you will turn it On everythings work as Normal
But After a good time 2 or 3 hours approximal it will turn off automaticly off And the problem is back
If someone have solution post it here
I try To restore And i try it with jailbroken device and normal device no solution
Thank you ...
