Keep in mind that AIM and MSN are the two most popular IM services in the United States. As it was with the Yahoo offering, I'm sure that there will be an exclusive period, although I'm not willing to bet a dime that T-Mobile, and especially Cingular, jumps on board for that exclusive period.
Anyhow, back to your question, no. These IM clients should operate based on service books (guaranteed for the MSN client, as you can read above in the images). The carriers control which service books are sent to the handhelds and which aren't. Someone (no names) has had some success in populating a service book from one handheld to another with a SIM swap method, but I've not heard about this from anyone else (although the reputation behind this someone is unquestionable at this point in time ...and he's a good friend, too). I'd test if I had a Cingular account and an unlocked phone, but I have neither.
