I'll never use Nimbuzz. Maybe it's my lead foil hat but I don't want all of my passwords, conversations, data, etc. collected in one place, by one company like that.

Beejive worked when I used it but it did have issues* on my -then- unflashed Omnia. Maybe they've been corrected by now.

*Phone stopped waking with front button even went set.

edit: You're only charged (in the form of a txt msg) for IM's sent using the multi-client that comes with the VZ i910. 3rd party IM clients are just data plan usage. I was concerned before I had unlimited text but it checks out.
