Some people love the iPhone in its entirety – except for one thing – the lack of a physical QWERTY keyboard. With the Nuu Mini Key, it is an accessory worth looking into if you’re one who wants to pick up a physical QWERTY keyboard for the iPhone. Making a debut at IFA 2010 in Berlin, the Nuu Mini Key protective case will not only double up as a solution for the iPhone 4’s reception issues but also doubles up as flip-out QWERTY keyboard. One can only assume that this will hook up to the iPhone’s dock connector which adds a considerable amount of bulk to the bottom of the case, but the benefits could very well be worth it. It has been stated that the keyboard includes a Bluetooth v2.0 class 2 and HID profile compliant Broadcom chip alongside an integrated rechargeable battery that will power the keyboard’s backlight so that the iPhone’s battery will not be under additional strain. Expect the Nuu Mini Key to hit the market sometime this Christmas for $69.
