Hi all, I've been trying to jailbreak a new ATT iPhone 4 for the last several hours with no luck. Unfortunately I'm stuck with iOS version 4.3 (don't have SHSHs for previous versions). I'm a Mac user, and followed the steps outlined in this article: http://www.iphonefirmware.com/2011/...reak-ios-4-3-gm-on-iphone-4-using-pwnagetool/ I tried using both the listed version of Ramdisk Fixer (1.5) and the new one (1.6) which I was pointed to while building the custom ipsw in Pwnage 4.2. I got everything working, except I'm unable to restore the custom ipsw (iPhone3,1_4.3_8F190_Custom_Restore.ipsw) from iTunes. I tried editing the hosts file, commenting and uncommenting the lines for Apple's server: #18.104.22.168 gs.apple.com #127.0.0.1 gs.apple.com When both lines are commented (as shown above) I keep getting Error (1). When I uncomment the first line (points to Cydia's server) I get Error (1600). The whole point why I'm trying to jailbreak the phone is because I relocated overseas and I need to unlock the phone in order to use a local carrier. But I don't think there's any way to unlock an iPhone without jailbreaking it first. Any ideas or suggestions of what may be going wrong are greatly appreciated. These are the details of my device: iPhone 4 Model MC318LL iOS Version 4.3 Modem firmware: 04.10.01 Thanks.
