iPod gadgets are big business and this cool gadget for the iPod looks to be a sure seller. The AquaTune submergible speakers from Focal allow iPod connectivity for all of your underwater music needs. The Nano 4G model works with the latest iPod nano and has a pair of 1-watt speakers. The V2 model (pictured) is compatible with additional iPod models and has a 3-watt x 2 power rating.

Both models use clear, polycarbonate bodies and o-ring seals to prevent leakage and a flexible silicon rubber membrane that enables operation of the Click Wheel. They are submersible up to one meter for half an hour; any longer or deeper, and the seal may be compromised.

The larger V2 model is compatible with Apple’s fourth and fifth generation iPods, first through fourth generation iPod nanos, iPod classic, first and second generation iPod shuffle, and the iPod mini. The AquaTune Nano 4G and V2 are currently available in Japan and will be available stateside for $175 and $120, respectively.

An Apple iPhone 3G made of 18 carat gold and encrusted with diamonds is laying claim to the title of the world’s most expensive phone. It was coming wasn’t it! Where there’s gold, diamonds are sure to follow.

It’s become a familiar pattern, as we saw most recently with an 18k gold Shuffle that was soon followed by a diamond encrusted version. So it was time to start an office pool after a 24k iPhone began making the rounds a few weeks ago.

In classically over-the-top fashion, the U.K. purveyor has adorned this limited edition with 420 diamonds totaling 5.65 carats set in 18k white or yellow gold, with a choice of white, black or pink sapphires. Decisions, decisions! With a price tag of $41,225 price, it laughs in the face of the credit crunch.

Designed by Austrian jeweller Peter Aloisson the customised iPhone is priced at £1.6 million. The handset is surrounded by a white gold line encrusted with a total of 138 brilliant cut diamonds of the best quality.

But the most prominent feature of the “Kings button” phone is its home button that features a rare 6.6 carat diamond.
