Hey guys, I need some help. My mother recently gave me her old iPhone 4s and I rested it and upgraded it to iOS 8.1. After the upgrade, iTunes showed that there were about 3 or 4 gb of "other" space taken up even though I literally had nothing on the phone. I began to download a few apps (3 or 4 small ones) and I put two albums on the phone and the "other" space grew exponentially to 7,5 gb. Can someone tell me what's going on and hopefully how I can fix this?
