Well, I just discovered something rather annoying on the iPhone 4S.
This morning, AT&T 3G service in our area hit the wall in a very nasty way. First data services went out, and now, no audio during voice calls... but, phones are still showing full bars! So, AT&T's 3G cell sites are transmitting loud and proud, but they don't seem to be connected to anything functional. iMessage works but only through WiFi.
No problem, I think to myself, we'll just drop to EDGE and see if that's any better...
And then I tried to turn off 3G. It appears that you can't on the iPhone 4S.
My girlfriend discovered this leaving my house this morning on her way to work. She's still new to the area so she needed her GPS app on her iPhone to get directions... unfortunately, the app requires data. 3G data is down, so no dice.
She tries calling me, and my phone rings and we can see the call is connected, but we both get silence.
She freaks out but manages to pull into a McDonalds parking lot, which thankfully has free Wifi. So she was able to iMessage me her situtation and then establish facetime where audilo and video both worked, and use the WiFi to at least get the maps app to give her a route she can write down and be on her way.
And sure enough, I can't make any voice calls, to any number... they connect but, there's silence. Same with her phone. We can dial using the keypad INTO the call, and hear our touch tones bounce back, so we know that SOME level of audio is working and it's not our phones. FaceTime also confirms this.
This is probably the first time in a long time that I've had a real gripe with AT&T. And I'd love to know if the old EDGE network in our area is similarly hosed this morning. Too bad I can't anymore!
Anyone know if there IS a way to shut off 3G and drop to EDGE on the 4S? Because I can't find it!
(Note: "Turn off cellular data" is not what I'm looking for. that turns off cellular data all right, but the phone stays on the 3G network, which doesn't solve my problem).
