One night i was using my ipad and i was tired, i put it to sleep, and went to sleep myself, as anyone would do. That night my ipad had 2.86gb free. Then in the morning i wake up to find it only had 2.32gb free. How could half a gb just disappear? My ipad is slowly losing space! Ive notice every few hours or so i lose a few mb. Think it might be virus,if there are viruses (ive heard there arent any for the ipad). Any ideas? Just so you know i have an ipad 2 5.0.1 absinthe.
