iMessage no longer working after iOS7 update.

If like me you have upgraded to iOS7 you may find that iMessage is no longer sending & receiving messages.

There is however a simple "fix" for this which is to reset your network settings.

This will reset your mobile data settings and also clear any WiFi network saved settings that you have. The mobile settings will automatically be assigned again but you will need to reconnect your WiFi networks.

To reset the network settings follow this simple guide.

1. Settings
2. General
3. Reset (it is at the bottom of the list)
4. Reset Network Settings

Your device will now reboot and then iMessage will then work again!
