Another thing ive noticed when updating ios while jailbroken. If u update, it takes away jailbrake BUT all the jailbrake app files, folders, etc... Are still retained in ipad internal memory. I discovered this one time a few jailbrakes back. I was like wth all my memory go. With new update and jailbreak gone, i should have a ton of new memory left. I confirmed it on new jailbreak n used ifiles to go into internal files/folders. Behold, all my movies, emulator roms, and etc.. Was still in there without me having redownloading/placing them in there again. So be careful or uninstall all cydia apps b4 upgrading the ios. Also, if u dont, when u do the new jailbreak, it makes duplicate jailbreak files since original ones still in there. I had to do some early spring cleaning in the ipad internally once i discovered that also. How did i know which files to deletE? By looking at the date of the install. The older duplicate files had dates from a previous jailbrake. New jailbreak had a more recent date. Hope that helps for those who dont know and another great reason Ifiles is needed.
