I have had it jailbroken for the past month. I just switched up the theme for a glasskart theme and changed my font. I also use backgrounder, kirake for multitasking. Recently my phone has been acting up, freezing, apps shutting down automatically just normal jailbroken glitches. I just realized that it definitely is not running as smooth as it was when I originally had it and it was all stock. I am debating on if it is worth going back, I only use pandora to run in the background really. Has anyone been in my boat before?
