IOS 6.0.2 update - iMessage stopped working

With the 6.0.2 iMessage stopped working. I reset the network settings but still no luck. Anyone else facing this problem?

I am not sure if we are the minority here but try if this works for you. It's the prescribed solution but it hasn't worked for me. I am currently roaming out of network so maybe that is one issue but will update the thread when I am back in my home network.

1. Shut down wifi.
2. Turn off iMessage and Facetime.
3. Go to Settings > General > Reset > Reset Network Settings. This will restart the phone. Doesn't delete any data so you are fine.
4. DO NOT Turn on wifi yet.
5. Turn on iMessage and "patiently wait for the activation.
6. If #5 successful then turn on facetime.

Let me know how it goes.

Thanks,

Update - I am not sure if most of you knew this but I certainly didn't. If you change your number it takes up to 30 days for that old number to time out from iMessage. The way you can avoid this is to turn off iMessage and FaceTime before you change to the new number.

I am not sure now if the update caused this because I changed to the new number at the same time I updated to a new phone number. I called apple care and they explained that it could take some time for the old number to sign out.

I will update this thread once my old number times out. Hopefully this is the root cause for me.
