Lots of moving pieces on this one, so I am not sure what the real culprit is. Updated my iTunes the other day to the latest version, upgraded an iPhone and my iPad to iOS 8.1 and jailbroke both devices. Now when I connect the two devices, the storage indicator bar in iTunes (the one that tells you that X GB of data is used by pictures, Y GB of data is used by apps, etc) is screwed up and tells me that I have 48GB free space (both devices are 64GB). On my iPad it initially displayed the correct amount of free space (about 6GB last night), but when I hit the sync button it suddenly claimed the 48GB again. I have another jailbroken iPhone that is still on iOS 7.06 where the data analysis/display is working. Is anyone else seeing this as well?
