I have a Cingular 7290 and upgraded to the newest software from T-mobile last night. I now have a new application, BlackBerry Messenger, on my device. This is RIM software included with the handheld upgrade - NOT T-mobile stuff.

Apparently it is only for blackberry-to-blackberry, but it seems pretty cool. You not only get the checkmark with "D", but it also turns to "R" for read!! (just like Cingular Interactive's "ipages" or Interative Messaging on the old 950s and 957s). There's also an option to "PING" the user. It causes the other blackberry to vibrate real short and quick - similar to the BUZZ feature on Yahoo messenger.

A couple of tips:

-Hit the symbol key twice to see all the little emoticons you can use
-Go to Pictures and click on a picture, select "Send to Messenger Contact..." to send to another BB Messenger user.
