This would be more interesting if we didn't pay 40 cents every time I sent Emily a text message.
As it is, the most curious part is how they enable Gmail to receive SMS messages ...
Official Gmail Blog: Really new in Labs this time: SMS Text Messaging for chatMy interpretation of this cryptic announcement is that the first time you use Gmail to send an SMS message, your Gmail identifier is assigned a unique 406 phone number. From that moment on SMS to that number go to Gmail.
... On the receiving end, when you get a text message from Gmail on your phone, it will come from a number in the 406 area code... You can reply to this text on your phone just like you'd reply to any other text. The reply gets routed back to our Gmail servers and shows up in your friend's Gmail chat window...
... messages will come from a [unique] 406 number so you can reply to any message and it will get back to the right person. Messages from the same person will always come from the same number, so you can even bookmark it in your phone....
Makes me wonder if there's a GrandCentral angle to all this.
It's not clear whether other phones, with whom you've never communicated, can use that unique number to send Gmail an SMS.
From my perspective this is backwards. I want Google instant messaging on my iPhone, I don't want to bother with SMS at all.
Update: Chris, in comments, notes that 406 is Montana's area code (I also had a 404 typo I've corrected). They chose it to get lots of free numbers.

The 406 area code is the entire state of Montana. They got more than enough spare numbers to go around up there.
i suspect that this means the number is unique *for the recipient*. in other words, if person A gets a txt from 406 111 2222, that is always the same person. person B might get a txt from 406 111 2222 and it would be an entirely different gmail account. to the recipient, the non-uniqueness wouldnt matter.
this would make way more sense, even if google bought every montana phone number, they would likely run out. but using the pair (recipient, phonenumber) as the unique key, they can probably get away with only needing a few hundred (or thousand) phone numbers.
Funny how we are learning that his 406 number is now used for the same general idea only for google voice calling and SMS
