I love testing applications so as seen this app is in java form then why not to give a try on my n79,its working fine on my N79 only few problem like in Login screen as n79 didn't have keyboard u can't input symbol through * key so i used key 1 :) and there is bug maybe on n79 on only that when ur signed in any community and went to start page where it ask to add other communities then there no way to get into previous stage (signed community).
This app works great on wifi speed is great,but as I get on Edge receiving message from friends take very very long and sending is slow too.
