I wish this fixed the oversized OTHER problem!
I have a 64GB iPhone 4S with about 10 gigs of apps and 17GB of OTHER. I've heard it is data but I know I don't have that much. I did the 6.01 update on my Mac (I normally turn iCloud off for updates, backup to my MBP, then install the update. I figure restoring from the laptop is faster than from WiFi. Right after installing my 4S showed 53GB of OTHER, with nothing else, but everything appeared normal on the iPhone. Turned Sync to iCloud back on, and resynced, and it's all back the way it was, but with 17GB of other. I've done a restore, restoring from backup, but it didn't work. I could do a clean install, but hate to lose all my game progess on some games.
Does anyone know if restoring from iCloud would get rid of this? I'd like the 15GB of free space I used to have.
Update: After scouring the web and finding nothing that would help, I fixed this. Restoring from iCloud vs the computer got rid of the huge OTHER partition. I now have 1.87 GB, but that beats 17GB. I now have an extra 15.3 GB of space on my iPhone! Once I restored, I did get a message that it couldn't be completely done, I did see all the app icons on the iPhone, even though they hadn't all downloaded. It said you could restore from iTunes. DO THIS WITHOUT changing the Backup to this computer. This way you won't reintroduce the corrupt data, but you will download everything that is on the computer to save hours of time. Hope this helps someone.
