I keep trying to do this and every time the process gets stuck in iTunes when its trying to verify the upgrade with Apple. Then it says it can't do that. I tried to sign out and back in to my iTunes account and now i get another messages: this device is not eligible for this build. WTF??? I have a jailbroken iPhone 4 with 4.1 firmware. Did it before with PwnageTool on MAC. No idea what is wrong with this as i've done this since OS 2.0... Any ideas? Anyone?

You need to add : gs.apple.com to your hosts file. And then try to use iTunes again(restore custom). Apple has stopped signing 4.2.1

Thanks for your reply! Just so I understand: i don't actually have to already be at 4.2.1 in order to restore to a custom 4.2.1, right? Someone told me that its failing because of that. Because I'm currently at 4.1. Is this right? I don't need to already be at 4.2.1? If i add this entry to my hosts file - the restore should work?

Hi Helper. For us non technical folk can you please describe how to "add : gs.apple.com to your hosts". I am having the same problem as kompuntu. Thanks!

@Helper I added the gs.apple.com to my hosts file, and still getting the same error "the iphone ***** could not be restored. this device isn't eligible for the requested build" Any other sugestions?

Run redsn0w and Select "install cydia" and make sure it's the only box checked. No need to restore or anything, just run the latest redsn0w and when it asks you to select a firmware file, make sure you point it to your STOCK 4.2.1 firmware file. @adamthepizzaman

I had the same problem with cydia not opening i just re-jailbroke and made certain i followed the instructions and it worked...AT&T iphone 4 w/4.2.1
Shasudi - March 4, 2011 at 2:04am
Install Cydia from custom packages and not from General in Pwnage Tool
kristianto - February 22, 2011 at 4:09am
why if I already jailbreak with redsnow, is any problem if I jailbreak again with pwnage tool?
bloodyfool0 - February 20, 2011 at 11:15pm
Worked just fine for me. Thank you iClarified for the very clear instructions. I would like to add that you should backup your data in iTunes before JB. After JB, restore the data you backed up in iTunes. I needed to do that to put all the files/musc/contacts back into the iPhone.
