ipsw

Im downloading for use with Redsn0w .9b8 jailbreaking iOS 5... I must use the iOS 5 Ipsw to jailbreak my iPod touch 3G 5.0.1 because 5.0.1 firmware isnt supported on redsn0w... When I download the ipsw for ios 5, it takes like 40 mins to download. Then when I finally have it downloaded it I go...

or do you have to re download it in iTunes?

I want to know if virtual machines can run iPod and iPhone softwares. If you have any, step by step instructions or links would be deeply appreciated. Thank you :)

When I download the file that is supposed to contain the ipsw, the ipsw isn't there. Ive tried downloading from different sites. No luck. Am I doing something wrong?

It has to be an ipsw file. I have searched all over the internet and only found .zip files

I need it to jailbreak my iphone 3g but can't find the .ipsw file and can only find the download which has a file with loads of .DMG files and useless thing in it. I have already loaded iOS 4.0 onto the phone but I need the .ipsw file to jailbreak it. Thanks In Advanced...

I have a 2nd generation iPod touch and I need to create an ipsw file FROM my iPod, so I can jailbreak it using redsn0w 0.9.5b5-5. (I need my ipsw file in order to fix the iBooks issue with a second jailbreak)
