I found a broken iPhone once. I held on to it for a while thinking I could maybe the battery could be useful for a friend, but I think in the end I just tossed it.
So I popped a battery into that camera last night, and it "worked"! The pictures were horrendous though, even at 640x480 they were blurry, and dim. Like one reviewer at amazon said, I guess you have to get outside in natural daylight to get anything reasonable. Anyways, the kids might have a little fun with it.
