I wanted to download the latest update to Garage Band, but I don't have enough available memory for the update. Icloud indicates that I have 4 gigs of available storage in the cloud. I have already deleted every app that I could do without, but still, my Ipad 2 (16 gigs) doesn't have enough memory available. How do I utilize storage in the cloud to store apps and updates? On a related note, is there anything available such as an external hard drive or an adaptor for a thumb drive that would work with an Ipad? Or do I have to sell my current device and buy a 32gig Ipad 3 or 4? Or is it 5?
