    After that long wait for a jailbreak on ios5(5.0/5.0.1) I don't think anyone is dumb enough to upgrade to 5.1

    so here's what happened. yesterday i tried to restore my unlocked 3gs with custom 5.0.1 firmware i created with sn0wbreeze and at the verifying firmware with apple i got an unknown error (6). The phone is now stuck at restore mode. I tried to kick it out of restore mode using the restore fix in redsn0w without luck. i then tried to restore using the custom 5.1 firmware created with redsn0w that just been released. Itunes can't get pass the verifying process after extracting the file and gives me unknown error (3194). Is there any help??? TIA

    Check your host file entries and comment anything with *.apple.com as it looks like your computer is pointing to Cydia servers or the other option is to try it on another computer ideally that hasn't been used for jailbreaking.

    I really hope this 5.1 solves the calling audio bug. It's damn frustating.

    No untether = no jailbreak for many. It'd be interesting to see how dependent sales on Cydia are on a truly reliable untethered jailbreak. My guess is fewer are bothering to spend money when they have only a tethered jailbreak. It has to come down to money at some point; money changes everything. Unless an untethered jailbreak is released I can't imagine developers would take the time to release something via Cydia.

    Thanks for the reply but what do you mean by comment anything with *.apple.com? And how do I check for the host file entries? I may try again using different computer today. But if you can elaborate more on the first option that would be great. Thanks again

    If you have tiny umbrella installed on your computer, open it and click on Advanced tab. Uncheck "set host to cydia on exit". Apply changes and reboot computer. You can now restore to 5.1

    You may need to run Redsnow and choose the option to Just Boot. Since it's a tethered JB, that is necessary.

    Just to add, Redsnow tells you after you JB that you will have go through the Just Boot process. Then Cydia and everything else should work. It did for me and always has in a tethered situation.

    i believe that you have to wait for the the update of ultrasn0w because its recent version is not for 5.1 but only support up to 5.0.1. If what mentioned in the other post is correct, new version of ultrasn0w will be released in a few days

    Hey Hardeep,The assumption of this guide is that you're on iOS 5.1. So if you're on iOS 4.1, you will need to update to iOS 5.1 and then use this guide. But before you upgrade you need to remember that this is a tethered jailbreak so you will need to connect your iPhone to the computer for every reboot (using Redsn0w). This guide is also not meant for unlockers so don't update to iOS 5.1 if you care about software unlocking your iPhone.

    You need to ensure there is no host file entries pointing to Cydia (check etc/hosts).
