Oh man, that thing is actually for real. Brando is offering a 6x zoom telescope for the Apple iPhone 3G. The lens is attached to your phone via a plastic case and my gosh does that look retared. But heck, it should do the job.
You can get it over at Brando for $19, there are even pictures to illustrate the zooming capabilities of this cheap lens.
