Halloween is just around the corner. There’s no reason you can’t dress your gadgets up in something spooky as well. Here are some cool Halloween costumes for your iPhone 3G or 3G S. The Demon Silicone Series Case for iPhone 3G/ 3GS turns your iPhone into a demon complete with horns.

In front it looks like your iPhone is being eaten, and on the back there is an image of a demon with hands. And of course, the case glows in the dark. The Demon Silicone Case comes in blue, yellow, white, green, and purple.

So you are a member of that ultra elite rocking corp, known as the KISS army. You watch Gene Simmons’ show and you feel required to buy any and all merchandise. Feast your eyes on this little monstrosity. It’s the Demon from the I-Dog KISS Kollection. This little guy will rock all night and party every day, never taking off his make-up.

This portable KISS pooch plays back music through his built-in speaker or your headphones. He’ll also entertain you with colorful electronic lights, expressive movements and sounds based on the music you play. Sadly, his tongue won’t roll out and hit the floor, before assaulting your girlfriend.
