Earlier, we referred you to a blog post by Marco Arment showing that iOS 5 could delete the contents of an app’s caches folder and temporary folder behind the app’s back, thus leaving the app with no safe place to store data. Now, MacRumors reports that the release notes for the beta of iOS 5.0.1 say that it “introduces a new way for developers to specify files that should remain on device, even in low storage situations.” This should fix the problem Marco described. iOS 5 will also bring back multitasking gestures to the original iPad, and is said to address the infamous battery life issue. follow link
