Windows 7 isn't released until later this year, but if you want to become an early adopter then check out this Windows 7 Theme for Series 60 phones.
The theme is an homage to the new operating system, adding a display background based around the desktop wallpaper in Windows 7. It makes for a cool-looking background, but it's let down by the horrible logo used, which is so squashed up that it just looks ridiculous.
Other changes the Windows 7 Theme applies to your phone include a smart new analog clock skin, some rather crudely-designed menu icons and neat pop-up menus.
Some of the design elements in the Windows 7 Theme work well, others are pretty lame. Let's hope the real thing looks a bit better!
