iOS5 update causes over capacity problem?

Thanks. That solution worked like a charm.

Update: Took the plunge and hit "Restore" in iTunes, then opted for the pre-iOS5-upgrade backup to restore with once the iPhone had been (quite quickly!) cleared and restored. It is now churning through a proper restore of all content, including putting the Apps back where I had them organised to originally, and "Other" is back to the more normal (for my iPhone) 0.7GB.

I also did the same... backup & restore worked for me. Checking the checkboxes mentioned by others did not work for me.

I just posted a question on this, before experimenting with itunes. Check you're apps that you're sync in the apps tab, I don't know why, iTunes was trying to sync everyone I've ever downloaded (around 900). I got rid of them and my memory is back to normal!! Don't know why this happened. hopefully my iPod's back to normal now!!

I just closed itunes and started it back up it fixed over capacity problem, without restoring anything hope it helps

A restore fixed mine too. Funny I was also going to use a pre-iOS 5 backup but it didn't offer me one. It only offered me a single iPhone backup to choose from???

Thanks Bro! worked just the way u said!!

I think it's fair to say either a re-sync or restore will fix the problem. For me, I had this problem when upgrading my 32GB 3GS. For me, I changed the sync options so that only my apps were syncing and everything else was removed from my phone. Only when all (90%) the space was freed up did my "Other" (18GB) disappear and I was able to sync all my stuff back to my phone. Luckily no iphone restore was needed for me.

Mine was fixed by restoring as well.

has to be a bug. trying to restore. hours of getting my music back on to come. is it me or is Apple getting sloppy?

Had the exact same problem today, I had 11.3gb free on my iPhone and now I'm over capacity by 0.40gb. Absolutely ridiculous.

I unplugged my iPhone from the computer. closed down iTunes, and plugged my phone back in. iTunes started up and the proper storage usage showed on screen.

Try this:

1) Uncheck "Sync Music" and sync. My Other file dropped from 14gb to .61 gb

2) Recheck "Sync Music" and resync.

It seems that the issue is possibly with all of the artwork that got copied across during the iOS5 upgrade.

I tried multiple things before stumbling across a previous post that recommended unchecking everything but apps. I didn't want to lose ringtone configurations etc, so I just tried music and it seemed to work for me.

Many of the above solutions might do the trick. But I just kept my iPhone connected, didn't do anything, and it corrected itself after about 8-10 minutes. The "Other" capacity overload went away and my iPhone is syncing like normal.

I had the over capacity issue also. In my case it turned out that on the first Summary page in iTunes, under the Options category, the checkbox for 'Prefer standard definition videos' was no longer checked, and it was trying to load HD versions of a lot of TV shows. Re-checking that got my usage back down to where it had been before the updates.
