Recently I have been playing modern combat 2 online and I have noticed that if I dont have a strong signal (not sitting right next to the router) while playing the game the wifi signal drops! Sometimes it happens when I'm right next to the router 2, just alot less. It is supper annoying and it's a problem from my iPhone not the Internet! It never drops the wifi when I am on safari or other Internet activities. I think it has to do with the fact that the iPhone and the router have a constant connection.... When I quit the game my wifi signal pops back up again!
