Let the iPhone 4 Keyboard case wars begin! We just reviewed ThinkGeek’s TK-421 Flipout Keyboard Case for the iPhone 4 and recently covered two other new iPhone 4 keyboards – the Nuu Keyboard and an iPhone 4 keyboard from Thanko. Now the TypeTop Bluetooth Mini Keyboard Case for iPhone 4 has showed up. It also sports a similar keyboard to the TK-421 but comes in a leather case with a flip-out stand for your iPhone, dedicated multimedia hotkeys and a 100 hour battery life. You can pick it up now for £29.95 in the U.K. and Europe. A French keyboard and German keyboard version are also available.
