As far as I can tell there are no true applications which work fluently in IOS4. Beejive and IM+ I've been reading a lot of complaints about. I had IM+ but every time I switched to it on the multi-task dock, it would take FOREVER to connect and sometimes not connect at all. I haven't tried Beejive in an effort to save my money. Meebo and ebuddy just have horrible connection issues and aren't fast at all. What do you all use?
