So Recently I have jailbroke my ipod touch 2g 8gb MC Model ios4. Since Apple doesn`t allow 2g models to have mulitasking, wallpaper, and battery percentage due to RAM and preformance. So when I jailbroke my ipod, I went on cydia and searched Features for (iPod Touch 2G). When I did that i got the full 4.0 function. But the last few days my ipods battery is decreasing fast than usuall. So What`s the problem?
