GoldenGadgets.com has the Portable Hybrid Solar Charger for Blackberry, iPhone, Nokia, etc for $20 + $3 shipping = $23 shipped. Solar Panels have charge and maintain the built-in 2000 mah Lithium ion battery inside, providing USB spec power for your devices.
So you can listen to tunes if one of those Die Hard 4 scenarios takes place and there's no electricity?
If you have an extra few days to wait recharging while living near the equator, without any clouds in the sky, and a supported phone that plays music, YES.
I suppose you could try carrying around a giant magnifying glass and some mirrors to concentrate the light on it more, though the more sane approach would be to buy a solar panel about 5X this size though they dont' generally come with the phone hookup kit so you may need to buy both and hack it out yourself. For example the following panel mounted on a piece of polycarbonate and wired in place of the panel included with this set.

They have a few other reasonable panels as well, providing more power per dollar in a couple cases but would mean buying 2 panels and wiring in parallel.
You just can't get enough power to do anything useful with modern electronics with a tiny panel. Maybe recharging an MP3 player that has a AAA cell battery would be easier to accomplish with something about 6" square.
#2, that site rocks, thank you for the post.
