What Is This So-called iPhone 4 "Game Grip" For Exactly?
Has anyone used a such a stuff as a "gaming grip"? I learned this name yesterday when I found a so-called one (http://www.tinydeal.com/gaming-contr...i--p-7878.html) for iPhone 4. I guessed it was an extra controller at the very beginning, but didn't find any button on it. Then I thought it was a rack, but i cannot see how to play game with it. So is there anyone to tell me about the grip? I am really interested in it.
