I've yesterday update iOS 5.0.1. I did it directly in phone without iTunes.


Today I've recognized a issue - my iPhone is loosing connection with Carrier.


I bought phone directly from Apple and using it in T-Mobile Czech republic network.

The status bar show only Search... or No Service


I'm in area where others have good signal including 3G. Also my iPhone 3GS and iPhone 4S before upgrade works well.



I have to switch off the phone (5sec. push of sleep button) and start again to find Carrier.

The switch to Plane mode and back doesn't work.

Manual choice of carrier doesn't work even I can see and choice T-Mobile - still no service



I need to revert iOS update to be able to use my phone. Please help me with this.




Best Regards


iPhone 4S, iOS 5.0.1
