you also get charged a message just for logging in to AIM, and one for updating your buddy list, and adding or deleting a buddy and logging out... Please be careful with this AIM feature as i have seen bills in the 1000.00s of dollars due to careless usage. Turning your phone off does not log you out of AIM, you are still connected to the server as far as AOL is concerned and therefor can still recieve messages and rack up a HUGE bill...
