The iCloud service now allows you to re-download any app you have previously purchased on any of your iOS devices includes killed apps. We tested out with iPhone 3GS along with iOS4.3.3 and checked out the Purchases section. We had found an app we have purchased and removed from appstore in nearly more than 3 years, we press the iCloud icon within seconds we got it back in action. Sure, it is really an enjoyable one.
