Matt Croydon rightly castigates the hype about trans-Atlantic texting finally working, after all he and I have been exchanging messages for quite a while, I suppose the real story is in interoperability between GSM and some of the whacky home-brew cellphone networks that the Americans love to use. GSM to GSM invariably just works.
Thinking about it I used to regularly exchange SMS with some of my mates in Australia around 7 years ago, hell I even used a great Australian SMS-email gatewaying (and much more) service run by some Melbourne based chaps called eFone, it used to puzzle the hell out of folks when I gave them a .au email address for sending messages to my phone in the UK!
