There are plenty of generic solar chargers for all mobile phones available, but few designed specifically for the iPhone. Here’s a new one from SolLight: the SOLiCharger, going for $39.95. Four hours of direct sunlight will charge your phone, but you can also power it up via USB. This thing looks like a nice, compact way of keeping some extra power around – it’s juts a shame that you have to resort to third-party accessories since the iPhone’s battery isn’t removable.
