IM+ doesn't work properly on the Bold OS6. It thinks you are using a Torch and displays some touch buttons that you can't press. Also, the menu will not come up so there is no way to exit it either.
I tried Meebo. It works but it doesn't have an audible alert sound for new messages and that is annoying. Nimbuzz works just fine for me.
