Giant "other" usage on iPhone. How do I recover this space?
I am running iOS 5.1.1 on my 16GB iPhone4. iTunes reports 3.4 GB of space used as "other". I have deleted all of my text messages, a bunch of PDFs, and many apps but this has not made a dent. My few apps that DO store data do not have enough files to come close to this amount.
Researching this problem has led to to believe that I need to backup, reset, and restore the device. However, I am not ready to migrate to iOS6 yet. Is there any way to either recover the lost stoarge space OR restore my phone and still keep my current operating system?
This may or may not be pertinant, but I sync my phone on a WinXP box.
Please be gentle. This phone is NOT jailbroken, I just prefer iOS 5.1.1 for now.
Thank you for any guidance you can offer.
iPhone 4, iOS 5.1.1
