Not sure exactly which devices are compatible with this theme but I am sure It works on the Curve and Pearl series devices. The theme is actually quite slick and is designed by Scott Campbell the Tattoo artist. Scott is releasing a new line of decal stickers (called tattoos) for BlackBerry but I have not managed to find them anywhere even though I saw them at the RIM booth.
Personally I thought the theme had some serious promise but at the same time has some basic flaws. The dark look is slick many of the icons are hard to tell apart. There is also the problem that many of the basic 3rd party icons such as Google talk ruin the whole look. The date is also hard to read in the thin italicized font.
The theme is only available during CES and can only be downloaded from you BlackBerry by going to the link http://m.kargo.com. The theme is larger than half a megabyte so I would not recommend this for those on limited data plans.
