Trying to jailbreak/unlock my iphone 3g running 4.2.1 with 5.15.04. I realize that I need to use redsnow to jailbreak and upgrade to ipad firmware. Downloaded 3 different versions of redsnow: redsn0w_mac_0.9.6rc16 redsn0w_mac_0.9.6rc17 redsn0w_mac_0.9.6rc18 Even downloaded redsn0w_mac_0.9.6rc19 but it doesn't seem to have the option to upgrade to ipad baseband. I go into DFU mode. Redsnow recognizes. But while it says it's fetching the ipad firmware, it just disappears. Am I doing something wrong? Stats below: iphone 3g 4.2.1 8c148 firmware 05.15.04 using macbook pro late 2007 OS X 10.6.8 Any help would be greatly appreciated. Going to England in 4 days and I want to use the phone there.
