So I was having a hard time with jailbreaking to 3.0 on my 2g iphone. Seeing as I was running vista on my laptop I thought trying on my XP machine would work out better, with no change. After Hours of repeating the process and getting to the "Downloading Jailbreak Data" and no response, or redsnow crashing (even on XP compatibility, and runing as Admin) Nothing would work. I took a day break after restoring to 2.2.1 I came back to my vista laptop and did the following 1. created a new administrator account on my vista machine 2. Made sure Itunes was 8.2 (I uninstalled and reinstalled which took forever but may have been part of my success in the end.) 3. Made sure IPSW was iPhone1,1_3.0_7A341_Restore 4. Made sure I had bootloaders 3.9 and 4.6 to unlock my phone as well. 5. Made sure iPhone1,1_3.0_7A341_Restore was not .zip but .ipsw 6. Upgraded to 3.0 OS and closed Itunes. 7. Downloaded a fresh copy redsnow 0.72 (unziped using WinRAR, but shouldnt make a difference how you unzip.) 8. Did not run redsnow.exe in compatibility mode or admin 9. opened redsnow.exe 10. Iphone was already connected from when I upgraded to 3.0. 11. Selected iPhone1,1_3.0_7A341_Restore as my current firmware 12.select both cydia install and unlock. 13. next browse to both 3.9 and 4.6 boot loaders 14. Hold power button until "Slide to power off" message appeared and then shut off. Wait till swirly thing has done its thing and dissapears. 15. proceded to enter DFU mode as per redsnow instructions 16. once you get to the part of DFU instructions where its asks you to hold home button for 30 seconds, even if your PC recognizes the iphone keep holding it till you countdown from 30 completely. 17. Let redsnow do its thing and wait till your iphone displays "Downloading jailbreak Data" including the swirly thingy from before when you turned your phone off. 18. after about 2 mins (some report 5-8mins) it should display running pinapple and you should be in the clear let it do its thing till you see springboard(iphone home page....if you will) and done. this solved my problems and jailbroke my Iphone 2g and hopefully this helps others out too. Let me know your results. Answers to questions that I know will be asked: q:Is this jailbreak tethered? a:no q:will it erase all my data? a: if in data you mean songs, contacts, sms chats, videos, cydia apps already installed, <redacted> and your custom theme you got for winter or summer board or whatever you kids are using. Then yes it will. Back anything up that you want to transffer over to your Jailbroken 3.0. q:will this unlock my iphone? a: Only if you are on 2g iphone and have the required 3.9 and 4.6 bootloaders. as for 3g Look up "Ultrasnow"
