Turn your iPhone into a DSLR. Photojojo.com or click the picture.
Tell the blackberry users to go F’ themselves. I did extensive research, there are about 3 of these slide-outs for the iPhone. This is the best one- “Nuu Minikey”. The extra screen real estate, especially with the industry’s highest resolution screen, can only be described as, amazing. I kid, bb users. Not really.
For the Blackberry converts: It slides out nice, sliding out activates the screen. It acts as a protector for the back. It doesn’t block the camera, which is key, it illuminates in the dark, looks like it was made for the iPhone, and is wireless (Bluetooth). You can also put it on it’s side to take pictures, where the iPhone is too skinny to do that. Down side: it’s bulky, 2 1/2 iPhone thickness
I’m waiting on the day the iPhone maps app can be opened and it will just “beam” you to your destination.
