I tried both Fring and Tango this weekend between iphone and android. No issues to report here. I will try between android and ipad, just to post the results, but should be the same.
My wife has the iPhone 3GS and she doesn't see me when using Fring. Since her phone only has a rear facing camers, her screen shows what her camera sees, not what mine is sending.
