We have seen the first Gingerbread operating system ported to other devices, while ports arrive to your Android device (if it comes), XDA member Longsh0t presents this set of icons, so you can have a taste of it with no more waiting. Using Launcher Pro and Folder Organizer, you can have Gingerbread icons like Angry Birds, Astro File Manager, Browser, Camera, Contacts, Documents to Go, Dropbox, Email, Engadget, Facebook, Gmail, Maps, Market, Phone, Shazam, Skype, Twitter, Youtube, and many more.
The developer is open to receive requests for more icons, so step in and please leave feedback.
