Okay, themed cell phones might not be your thing, but damn, Ericsson's Spiderman 3 phones are hawt.
The four models include the Cyber-Shot K800i, Cyber-Shot K550i, K750i, and the K610i. They come with 3 wall papers and a screen-saver, a carrying case and a hand strap. Sadly, this is expected to be a China exclusive. But still, look at the pics and want.
