My situation: my boyfriend let me borrow his jailbroken iTouch, and knowing nothing about them, I updated the software and lost it all. So I have 4.2.1 software now, so I looked up the jailbreak for that. I used redsn0w and I thought it worked perfectly, but after I used the "Just boot tethered right now" option, the pineapple came up and all, but it's just...stuck. It keeps making the little slide-bar noise every 10 seconds and it looks like it's been loading for 10 minutes. Also, I'm using an iPod touch 3g. Help?
