From the front it looks like any other iPhone 4, but flip it around and a glint might catch your eye — that’s the doing of Russian technology tailor Gresso, who’s embedded Swarovski crystals and an 18-karat golden Apple logo in a sheet of African Blackwood attached to the device. As usual, one wonders why anyone would bother, but honestly we can’t complain — the design is worlds more tasteful than the solid gold and diamond-encrusted contraptions we’re used to seeing. Expect the dainty dillantante to arrive in December at a surprisingly reasonable $3,500, or $3,000 for the male-targeted version at right. Of course, if you’ve got that kind of money to spend, you want one now, right? Good news: the iPhone 3GS gets the same luxurious treatment — and price — in July.
