Sorry guys, but I've read the stickies and I'm thoroughly confused on what to do with my particular configuration. I just got an iPhone 3GS under contract from AT&T running version 3.1 (7C144) with Modem Firmware 05.11.07 and my PC has Windows XP on it. I want to jailbreak it and avoid having to do a "tethered reboot" issue. I was under the impression that I could do this if I bought an iPhone with 3.1 on it. However, I'm not sure which tool I need to use and if I need to upgrade to v3.1.2 to jailbreak it. I find stuff for jailbreaking 3.0 and 3.1.2 and devices upgraded to 3.1.2, but nothing on 3.1 that was bought from AT&T. BTW, I don't have an issue upgrading to 3.1.2, just don't want to have the tethered reboot issue and want to make sure I use the right firmware. A little help for an iPhone newbie please.
