as i said in my previous post, why dont you try using mxit for android via nitdroid on your n900

found this http://www.androlib.com/android.appl...roid-qzCj.aspx
its about mxit for android, the ratings are 4 stars but a lot of comments said that it still suck... probably you would like to explore more into that possibility...

on how to install nitdroid, i personally have never tried it
try googling for nitdroid and youll find another forum that have a lot of information about it
