Do you feel a decrese in speed ? Worst battery life ? After 24 hours my iPhone 5 has no problem and I have installed a bunch of tweaks & apps (Zephyr, 3G Unrestricor, iFile, NCSettings, FastBlurredNotificationCenter, FiveIconDock). The performance is the same but I can't tell if the battery life is worst or the same. How is your i5 behaving ?
