Here's one that's a little out from left field; Puma has a solar-powered smartphone. Seriously. Sagem and Puma announced the device today at Mobile World Congress and fair play to Sagem, it's actually a pretty sexy looking device.
It packs a 2.8-inch, 240 x 320 QVGA touchscreen; a 3.2 megapixel camera with LED flash, x6 zoom and video capabilities; Bluetooth; GPS; compass; pedometer; Web browsing; email; SMS and MMS. The most unique feature is probably the integrated solar cell for charging.
Unfortunately, the gushy release doesn't mention OS, price or even a specific release date. All we know is that the Puma Phone will be available through European carriers and on PUMA Online from April 2010, with international markets to follow. See more here.
