iOS 6 is out – is it worth upgrading?
YES – for the single reason that finally you can see which apps are eating valuable space! I have always been frustrated by the fact that I can’t see which app was using space. But now iOS 6 resolves that.
Go into “Settings” > General > Usage and give it a few moments and it will show you each apps data usage (not just the app data itself but any other data stored within it).
