The 2nd gen iPod wasn’t supported on iOS 5.0 why would it be now? The last iOS for that iPod was 4.2.1 or 4.3.5.

I need to know if I will lose my installed APPS and preferences if I do this update? I am using Iphone 3GS 16GB running on iOS 5.0.1 and have the latest Itunes installed. I know about making backups etc and do so regularly, just need to know if my apps will stay installed AND their current preferences.
Please anyone confirm me asap.

This is not working for me.  I want to get rid of the jailbreak and go to 5.1 but itunes is telling me the device is not eligible for the build.
HELP ..  anyone know how I should restore this 4s and take it back to normal?

 @jtdesigns I have the same problem and have spent the las 18 hours straight looking for a solution, but it seem apple has stopped signing firmwares meaning those having custom firmwares cannot update :( this is really frustrating, I really want to get rid of the jb and go for the 5.1! HELP!!!


Joscha March 19, 2012 at 7:19 pm

 @jtdesigns The problem may be the redirection to Saurik’s server: For the Jailbreak to work, Tinyumbrella tells MacOS not to talk to Apple’s server for the authentication, but to Saurik. If you want to get rid of the Jailbreak and update to 5.1, you need to remove that redirection, so iTunes can talk to Apple’s authentication service again.
Solution: Use a text editor and open the file /etc/hosts
Look for the line that contains “apple” and write a “#” in front of it (without quotes). You will need admin rights for this. Restart your computer, and now the update should work.
