ok, i'm going to try to keep this short, but i'm terribly frustrated right now. in the efforts to track down and rid myself of the nasty 4.3 battery drain bug, i decided to do a "restore to factory" of my iphone and then rebuild from backup. when i did so, my phone ran out of space when it previously had 4-5 gb free space (32gb model). i've combed this site and the web to find solutions. most suggest that its some "orphaned files" that got lost in a partial sync. but my problem seems different that one others have noted previously. anyway, i thought i could solve it by removing the music and rebuilding the playlist again (having also wiped out the music directory structure using a tool like DiskAid), but that's just as bad: - as i add album by album new music, i see the space usage go up on the "other" category as much as it does for "audio/music." what the? i haven't seen any comment about this in particular, let alone a solution! anyone else encountered this? any fix? is this a problem with 4.3? 10.2.1 itunes? (i'm starting to have issues with my ipod touch too which was syncing last night to get a couple of apps and it ran out of space too -- it too is running 4.3 help!
