Cross talk sounds very cool, but until it is out, I will continue to use pingchat. I have had minor issues with pingchat as to getting pings in a resonable amount of time, but 90% of the time, it was because of something on the phone, not Pingchats servers. I will continue to use Pingchat as it is the only cross platform IM services that allows voice, pictures, texts, and group chat that I am aware of. It works with iOS, android, and BB as long as BB is 5.0 or higher. I have become very dependent on message reciepts.
