Get iOS 5 on your older generation iPhone/iPod with Whited00r

A new custom firmware called Whited00r lets you install portions of iOS 5 on older iPhone models.

Some highlights include iOS 5-style reminders, sounds, shadows, wallpapers and folders. It also jailbreaks your phone and provides a carrier unlock, if needed.

Whited00r brings a few modern improvements to the older iOS 3 and iOS 4 platforms to match the latest developments of iOS 5.
