It won't be in itunes. Find the folder or location where you download the ipsw. Then when you open up redsnow (the jailbreak software), you need to click on "extra" then select ipsw. Find the file that you just downloaded and it will begin to help you jailbreak the iphone.

Submitted by TheDarkSide (not verified) on February 8, 2013 - 11:53pm.

It appears that Apple has had all their vendors drop support for 4.2 and like the good little andriods (pun intended) they are, they turned their backsides on 3G users. (I have a feeling it was eigher drop 4.2 or be kicjed out of the store.

So if you want to stay a Jedi, it's time to tithe to the Big Apple in the sky and BUY ANOTHER OVERPRICED IPHONE. Like all greedy businessmen, Apple tempers all their goodness and rightousness by their lust for more and more bloody dollars.

If Apple is still continuing THIS ISSUE., I would still continue using this iPhone 3G.. i don't care about the apps that are running on iOS 4.3. as long as i can listen to music, making texts, and calls.. And also, I have GUN CLUB 2 running on iOS 4.2 .. :3
