Hello All, Need your help please !!! I have Iphone 3gs: version: 3.1.3 modem firmware: 05.12.01 bootrom: 359.3.2 Used f0recast v1.3 and it says baseband: 05.12.01 bootloader: 6.4_M3S2 Model: MC138 Jailbreakable?: YES (with Star/Jbme) Unlockable?: YES -(use ultrasn0w) According to the link below, I will be able to jailkbreak and unlock. Although, an original sim card needs to be insert. Could I use my working at&t from my sister to activate and then jailbreakme along with ultrasn0w to unlock? Also, is it untethered jailbreak or must be tethered every reboot? http://www.redmondpie.com/jailbreak...with-jailbreakme-2.0-star-how-to-guide-video/ Much appreciate for all inputs !!!
