Im about to jailbreak my ipod touch 2g mc. Im gonna use greenpois0n 4.2.1 Ive jailbroken before, but i need some refreshers. Lol Im still gonna be able to sync my ipod to my pc, and not worry about it deleting any cydia/cracked apps i have, right? Thats the only thing i worry about, cuz im constantly editing my music library. Lol. So i wanna be able to update that and not worry about it messing with my jailbreak Also, Has anyone used greenpois0n for 4.2.1? Is it any good? I cant find any reviews or anything online.
