Hello thar! I have an iPhone 3GS, with no sim card. I use it as an iPod. What is the latest jailbreak and is not tethered? I have 4.3.5 right now. Right now the jail break I am using is tethered and every time my iPhone dies I cry a little on the inside because I am just lazy to reboot it through my PC each time lol. If there is no new jailbreak available is there i way i can downgrade my software and get a jailbreak for that? Thaaaaanks yo!
