so i have my friends ipod touch, and he wants me to jailbreak it. no big deal i've jailbroken numerous iPhones. i went on to check his firmware and he is running 1.1.5, so i went on youtube and found how to get the upgrade for free for 2.0, 2.1, and 2.2. i'm just wondering if there is any preference for which firmware he uses (he just wants the app store) as far as which is best for jailbreaking (if any is better). i tried searching but nothing really addressed this topic completely. also when i download the ipsw firmware file, it won't allow me to click on it to update it when i click option + update in iTunes (on a mac) and when i unzip the file there are a bunch of files in the folder.
