We have many separated mini bluetooth keyboard compatible with iPhone 4. Now through the iPhone 4 wrap, the QWERTY keyboard is integrated with iPhone 4.
Altamash Jiwani, a designer from India came up with the wonderful design concept. As we can see, a QWERTY mini keyboard with slide design is placed on the bottom half of the iPhone 4 wrap. Whether you slide the keyboard out or not, you can type quickly through it. Apart from that, you also can sync or charge your iPhone through the female dock connector at the bottom of the keyboard.
At present, the iPhone 4 wrap with QWERTY keyboard is still at the prototype stage. All we can do is to wait patiently, or check out the available bluetooth keyboards such as the credit card-sized keyboard, palm-sized keyboard, and more.
