Deactivate iMessage without an iOS 5 Device?
A friend of mine got an iPhone 3GS which is damaged now.
So he turns back to an 3G which does not support iMessage.
He forgot to turn iMessage off, so my iPhone (4, iOS 5) always tried to send via iMessage.
How is he able do disable iMessage without iOS 5?
Thanks for your Help
