The photos don't show it, but I've received several iChat messages while testing this method out. Each one followed the 265-0xx pattern. In this particular example, the person I want to contact has the code 265-061.
After clearing all my text messages from my iPhone, I tuned it off for a while and did something else. A couple of hours later, I came back to try to send a text message to 265-061.

Sending a message to 265-061, which should go to the iChat ID I use for testing.
After I sent the message from my iPhone, my iChat client on my Mac got it seconds later. I typed a response, as shown below.

The iPhone initiated this session using the six-digit code number.
On my Mac, I replied to the message using iChat. It was sent as a text message to my iPhone, as shown below.
Mnemonics are fun!.
The six-digit codes that are generated are attached to users you have iChatted with and as far as I can tell, the codes are unique to each iPhone. In my example, 265-061 always goes to rugunlutula on AIM/iChat. On another iPhone I checked, 265-061 wasn't assigned to anyone.
I'm doing some research to find out how long the assigned number codes remain valid. If you can provide some insight, please post a comment.
I'm waiting to hear back from Apple on some questions I have about all of this. If you have knowledge you'd like to share, please post in the comments section below.
