    You can create a custom firmware for 4.1 with Sn0wbreeze 2.0.2. Then shift+restore to the custom fw in iTunes to get up to 4.1 jailbroken. 4.0/1 isn't very good for the 3G. 4.1 runs much better.

    Whatever you do, don't hit the upgrade button. You must shift+restore to a custom firmware.

    Edit: I forgot to mention, if you run into any errors during the restore to the custom fw, simply have iReb run and bypass the errors.

    If you have a 3G then redsn0w will jailbreak you for 4.1

    Fair enough, it's just a 2 step process now instead of 1:

    1. Buy a mac

    2. JB 4.1 with redsn0w

    If only I had a few hundred spare dollars to spare to get me a used Mac :P

    That's what I'm saving up for, a brand new MacBook Pro! One day I'll have one...Blew all my cash on iPhone 4's lol.

    Ok, then open Sn0wbreeze 2.0.2 and select that firmware you downloaded. Then follow the directions.
