USBFever.com has introduced the iPhone telescope with crystal case. The $18.99 kit enables you to zoom in on objects you'd like to take pictures of using your iPhone camera by a factor of 6x.
The device adds some bulk to the iPhone, but USBFever.com claims you can use it to take images of far-away objects, at sporting events and concerts, for example, or in travel. The telescoping lens also includes a clear case to protect the iPhone from getting damaged. The lens can be detached from the case for easier carrying.
