How does it work? The Whited00r dev team have basically built a custom version of Apple’s official iOS 5, specially catered towards the ARM6 family of Apple devices: the iPhone 2G & 3G, and the iPod Touch 1G and 2G. You just download the IPSW firmware and install it through iTunes, just like a regular software update. Here’s the installation guide: it’s dead simple.

Once your device has been restored using WhiteD00r 5.1, you’ll have most of iOS 5?s best features, including multitasking, reminders, a rough approximation of iCloud that uses Dropbox as a core, folders, Newsstand, and even custom wallpapers.

Sadly, though, there is a caveat. Notification Center doesn’t come along with the package, and you also lose out on the App Store (although you can still buy, download and install apps through iTunes).
