Thanks for your quick response and comments.
You should check Viber out - lol.
It seems to work really well for everyone else that I have talked to and it would be nice to get a confirmation. Are you using the Mr. X or Juggernaut rom?
Looking forward to a tweaked ICS - Any idea when it's coming out? The last I heard was the official rom was coming in Feb / March and it will probably take a few more weeks to get it cooked up to tasty perfection :-)
Cheers for a starting a very helpful thread.
