Great news coming from the updated App Store application featuring the new Purchased tab: as noticed by our reader Nicola, you can download, install and run apps no longer available in the App Store, like the original Tweetie 1 or Instapaper Free. The apps appear in your purchase history alongside the usual description and screenshots page.
Unfortunately, due to Twitter’s changes, Tweetie 1 doesn’t work anymore – still this looks like a great option to fill your app library with software developers removed from sale. It might also be a temporary glitch on Apple’s end – we’re not sure. But for now, you can download apps that don’t appear in the App Store listings.
