so i have an iPod touch 4g, and i wanna test out iOS 7, but not on my iPhone, or iPod. i don't wanna loose my jailbreaks. so i have iOS 7 theme, and iOS 6 lock screen installed, but i want to make it more like iOS 7. the tweak where it makes the wallpaper move with the device "forgot name" isn't working. it tells me to update, but cydia doesn't say i have any updates. any help?
