Hey guys, welll i just bought a refurbished ipod touch and it works alright but when i bought it, it wasnt jailbroken and i have done many attemps to do so. So i've researched for as long as i can remember and well i put it on recovery mode, plugged it onto the pc, and clicked recovery with shift, look for the firmware 2g 3.1.3, and next thing i know, some error # 3194 comes out that doesnt let me downgrade from 4.0 to 3.1.3. This is really pissing me off and i have tried it multiple timez. ugh. i really need on this and also on jailbreaking.(i dont own a pc right now so i wont be able to jailbreak with a pc so i would like to know if i can jailbreak it through wifi and if i do so, is there a way i can upgrade back to 4.0? PLEASE RESPOND! THANKS)
