My unlocked/jailbroken iphone had been running quite slow and had a multltiple second lag. I restored to the factory default and there is still 186.6 MB of "other" files left over according to iTunes. At first I felt it may be OS software, but instead of having the standard 7.27GB, I now have 7.09GB. How do I remove these left over files? I dont want to rehck everything just to find that I have to restore AGAIN and delete those files, furthermore it just plain bothers me! Some say its preference settings, but I find it hard to beleive that takes up 186 megabytes. Yes, I have deleted all voicemails, text messages, contacts etc. It would appear everything is gone accept for a few setting adjustments and the info it gives on iTunes. Please help this tired soul.
