When i don't want to sign onto my aim account but want to send someone a message. i have have the number 265010 saved in my contacts under AIM and, in my Threaded SMS app, in my quick messages list i keep some frequently used aim names with a colon after it. (eg. "Mybuddy:")
This way if i know someone is on, or they forward to there mobile, i just hit messaging, new, type aim, then select the name from my quick messages list. then i type my message and send. presto, i have used SMS to send a quick message to my friend. They can reply and then you can chat from there. when they reply it will come from a different short code. you can reply to the new short code but be sure whenever you start a new conversation you use 265010.
I don't use this often now that i use IM+ and a data plan but it comes in handy when i am on a call and need to message someone using SMS.
I am sure this info is posted somewhere here with all of the great info on the site but i hope this helps someone anyway. Happy messaging.
