I have a 32GB iPhone 4s. iTunes can't seem to keep straight how much space is left on it. It's been happening a lot, but here's an example: I just synced my iPhone with my computer both wirelessly and then with the cable. Then I go through the apps (on iTunes) and delete some of them. When I've selected the ones I don't want on the iPhone any more, it says I have 10+ GB of free space. This is after the thing at the bottom recalculates for the deselected apps. Then I sync, and it says I have 7.7 GB left in free space. This happens a lot, the amount of free space I have changes by a couple of GB. Anyone else have this problem or know how to fix it?
