Please Help me, i bought a Bnew ipodtouch last 3weeks ago, and then they jailbreak it. and then after a week, the upper lock button is kinda weird, when i'll press it, it automaticaly turned off. i called up the apple store, they said that do not jailbreak it,because maybe the games that they put it is have a virus. so. they change the unit. now, can i jailbreak it or not? please teach me how to jailbreak it. thanks..
