I'm on 3, my wife's on Vodafone, but our iPhones automatically use iMessage (the message displays in a blue background). Sometimes one of us will send the other a message and the other won't receive it for maybe five minutes, sometimes much longer, and we'll be wondering why we didn't get a reply.
Is this a "feature" of iMessage? Is there a better way to send instant messages, a better app or whatever? Or do we have to revert to making phone calls?
