Qik comes pre-installed on a lot of phones in the U.S. Whoever you're video-calling has to have Qik also. I'm guessing in Europe Qik would be a waste. It doesn't do anything that Skype (with video) doesn't do too. Microsoft also just bought them so I'd imagine it'll get absorbed in to Skype anyway.
I got a message to update it as well. Any ideas where it is located on the phone.
