I have an iPhone 4s with the latest release of 5.0.1 (9A406) and everything was working well until earlier today I reset my network settings because of slow 3G. When it came back up I noticed iMessages weren't working. From the iMessage settings it keeps saying authentication failed even if I retype my password correctly. FaceTime settings does the same thing. And the kicker is twitter settings aren't letting me login either though I can use the same user and password in tweetbot it just fine. The twitter app works but isn't updating.
Something has to be wrong with the iPhone authentications settings. Anyone have any ideas? Tried rebooting / resetting network.
Interesting resolution to this question. I was travelling out of state when I reset my network connect. I couldn't get imessage to work until I was back in my home city. This seems quite strange to me, but maybe these services are some how geo specific?
Using the same exact login info I couldn't authenticate to any of these services out of town (tried multiple times on 3g and wifi). As soon as I landed at home they worked right away.
