Green House’s “Mobile Telescope Lenz” is exactly what u will want for your cellphone. The Green House kit comes with an 8x zoom lens and a small tripod designed to accept most camera phones.

There isn’t alot of information on how to operate the device but apparently u have to line up the camera phone lens with the adapter (connected to the 8x zoom) and and then operate the zoom by manually twisting the add-on lens. The lens will be on retail for approximately $88.
