I have been looking for an "all-in-one" client for my BB for awhile. I'm gonna start with a free app to see if I really want to be that connected! My question is do I need to install all the IM apps on my phone or is having an account enough. If I have to install Yahoo, GTalk, AIM, MSN. and then the app it seems like that would be an huge battry drain. I'm guessing I just need accounts for the IM's I use but wanted to make sure before getting into it.

Thanks
DR
