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.

Who charges their devices during the day? Will this thing work off of moonlight?
