Q: iPhone 4S unable to turn off 3G?!

So now do you believe the iPhone has real and not fake 2G (E)?

Makes sense then, good call.

yes i do

but some preinstalled apps are crashing after update

anyone noticed the same?

Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.

Guys i still dont buy the whole "att turning off edge antennas" argument.....why is the 3g/2g toggle still on att iPhone 4??????

So with the update of IOS 5.1, the 3G toggle is officially available for all iphones. Guess your query is now answered

So you do not actually read any of the posts? Because the AT&T folks say that they did not get the 3G switch.

Well this is not just for the AT&T discussions is it ?  When i said officialy its generic, applicable to 4S users around the Globe !!! 

Reread what you wrote, you stated all iPhones and that is not the case.

IT HAS FINALY ARRIVED!!!!! update ur iphone 4s to 5.1 and u'll be able to turn off ur 3g through ur general - network setting

not yet... i have iphone 4s and i've upgrade it to iOS 5.1 . its still missing. i live in UK and i using 3 Mobile Provider..

The switch was in up to the GM build of 5.1, but it was removed when apple and AT&T decided to display 4G vs 3G

So if u want it, stick to a beta release of 5.1

I'm not switching to the public release of 5.1 until someone gets their head out of their #^##es and puts it back in.

Oke, but how can I downgrade my 5.1 iOS to 5.1 beta? I would like edge coverage, because i have to communicate with my phone number...

This can't be discussed here. Even if your could revert to a beta, the beta will eventually expire.
