    I tried redsn0w, everything worked except no signal. After spent hours with several restores and crashes, finally worked by using snowbreeze 2.5. I am convinced that there is definitely a bug in redsn0w.

    Why dont you do it yourself if your that bothered? One word CANT! If it wasnt for the dev team and others you wouldnt have jb your phone to wait for an unlock, so do it yourself or sit down and wait patiently in line like a good kid

    Guys,I just faced the same freezing issue during the RAMdisk update but found a quick and easy solution.Please run the application in Administrator and Windows XP SP3 compatibility mode.Cool, isn't it?

    It should be noted that for Windows 7 in order to get pass the ramdisk portion, set redsn0w compatibility to Windows XP Service Pack 3... Directions:Right click redsn0w.exe, click troubleshoot compatibility, click troubleshoot program, then select "the program worked in earlier versions of windows but won't install on run now" option. Select Windows XP service pack 3 and start the program. Save settings for current program and BAM!!! No ramdisk problems!

    Worked fine.No problems at all. Using MacBook Pro.Instructions were easy to follow and available on several sights--more or less the same.Thanks for the help!

    The entire jailbreak process went perfectly.My only problem is that when I try to restart my phone it simply refuses to boot past the apple logo.After a while of the apple logo, a spinning/loading circle icon appears on top of it, as if I just resprung, but it still refuses to load.

    It could be Sbsettings that caused it because I used that to restart this last time it crashed, I don't remember if I used it the first time however.

    Those who would like a visual walk-through for the jailbreak, try YouTube. I always use the posting by Dinozambas2. He's the best and make everything very simple and easy to understand even for the new people. Give it a try.

    @lost- Once you have downloaded the zip file change the extension to ".ipsw" from ".zip". Quite literally just rename the folder with .ipsw at the end and it will ask if you are sure etc. If this is still not working do to my computer, tools, folder options, view, and untick 'Hide Extension for known file types. Then try and rename it and all will be good :)
