to their defense, it does come up and state that InstantMessaging is trying to make an SMS connection and asks if you want to accept that firewall connection.
in the early days of the 7100, we were able to switch SMS to transport over GPRS. this stopped working a bit later. word from TMO customer care was that 'billing reasons' dictated the disabling (as opposed to technical reasons). the option, to this day, is still on the handheld to enable SMS over GPRS but it does not work.
after that was disabled, there was officially no reason to use the IM client forcefully provided with the handheld. my biggest gripe with it is not that it uses SMS (although that's pretty crappy) but that it will literally lock your handheld up for a few minutes upon boot/wipe. you have to remove the service book THEN the application and THEN reboot. its not like the damn handheld isn't slow enough as it is, but it gets to the point of stupidity dealing with this IM client. it is available for download for the 7290 and 8700 but not the 7100 - not sure why (aside from the obvious consumer appeal of the device).
