This is probably a stupid question, but is it free to jailbreak my iPod touch? I have the 2nd generation, 8GB iPod Touch, with iOS4. Is it possible to jailbreak this iPod, or will I have to downgrade my OS? Also, when I visited ziPhone (like everyone said), it said you had to purchase it for $29.99. Maybe I am just really naive, but I just assumed it was free to jailbreak an iPod. Can anyone assist me with this? Thanks!
