I agree with you Mthr...for contacts that have BBs, there is nothing better than BBM or PIN. It would not be sufficient to me to have to switch to YIM or JiveTalk instead of using the (supposedly) more reliable and convenient BBM/PIN.
JiveTalk is much more stable for me than YIM on the BB, and seemed like it was worth the fee, especially if you use more than one IM service. I did have to stop leaving it running because of all the spam messages I will get throughout the day, and apparently there's not a setting to only accept messages from friends. If it had that, I would use it again. Good program.
