For that apple users above, it's not IM+ problem, it runs fine on my BB and other phones , it just apple sucks, change the name to acai, it'll be better.
+Maria, how come forgetting eula? RIM is wrong when taking long respond to you, but It's good to filter all app without eula, this to protect consumer, and for quality control for the app too. What's the use having 400k app to browse while most of them junk app, open it up once, try, then delete. I like the way RIM control the app world.
