today i bought a itouch and it looks nice. i still have stock firmware on it. only reason i wanna jailbreak is because id like to have many things that ios 4 does not let the 8gb version have. so should i or not. what are the risks? will i be able to multitask. will it be safe. will apple lock it like iphones that have been jailbroken? thanks.ohh and how do you jailbreak?
