If you have ever installed an application that was later yanked from the App Store, you can now reinstall them thanks to a new iCloud feature in iOS 5 that lets you re-grab your iTunes purchases if you don’t have them downloaded on the device you are using. This might just be an error on Apple’s part, which could be fixed soon, but in the meantime you’ll be able to grab yourself a new copy of banned apps such as VLC Player or iDOS. This is a great opportunity for people who upgraded to a new firmware or restored their iPhone, iPod touch, or iPad to re-download the apps that they have most definitely missed.
Furthermore, Engadget reports that they were able to successfully install a copy of Tris, pulled more than three years ago, on an iPhone 3GS running stock iOS 4.3.3. This indicates that this might be a feature that is not just limited to the beta versions of iOS 5. If you’re running a version of iOS 4, you can try to reproduce this ability by tapping on Updates > Purchased in the App Store and re-downloading any applications you had that are no longer available on the App Store. If it works for you, feel free to share.
