iMessages Beta not working with some contacts

When trying to send a message to a contacts mobile number that's on iOS5 - It says that they're not available for iMessage.


Do you need their email address for it to work?

Yup, as I said in the OP he is on iOS5 and uses iMessage on his iP4 to message other iPhone users running iOS5 just fine.

No you don't need their email address, you can just send it to their mobile number. I believe by default iMessage is not turned on in iOS5, you may need to tell your friend to turn it on.

I have to text a few friends and ask then to turn it on.

But that's just it.. It IS on. There were about 6 people with iOS5 in my living room using iMessage on their iPhones.

I messaged everybody from my Macbook other than one person which said he's unavailable for iMessage (Even though he was using it right there and then)
