iPhone 4S is loosing connection with Carrier after iOS5 update

Hello,


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.



Thanks

Best Regards

Jirka

iPhone 4S, iOS 5.0.1

Did that really work??? I can't believe my eyes.... I have the same problem and I can't believe that this is really happening... It is an unforgivable bug in Apple.. I assume that Orange (my provider) won't want to give me a 128K SIM (I don't even know if I already have that one..), but if Orange don't want to give me (or even sell) I'll try to cut a 64K SIM.

Unless you don't recommend it to me....

I have just bought an Iphone4S iOS 5.1.1 64GB for me and an Iphone4S iOS 5.1.1 16GB for my wife and both of us were unable to make calls. I am in Brazil using carrier TIM.

Wifi is working fine. 3G is also OK. But I can not make or receive calls.

It seems to be a firmware or hardware issue. I decided to turn off 3G and now I can make and receive calls.

With 3G turned on, the telephone is useless. With 3G turned off, the telephone works!

Anyone knows if apple is aware of that? Are they going to release any patch?

I Have sa e problem... everything works BUT impossible to receive and/or call!!!

So you just updated your iPhone 4S to iOS 5 and you're having a problem making or receiving calls? That sounds a bit unlikely. If your problem is not related to updating to iOS 5, the subject of this thread, you may want to start your own thread.
