Jailbreak iOS 4.2.1 using Redsnow 0.9.6b4
why pay if you can do it alone, here's the tutorials http://www.macshared.com/?p=462#more-462 with included download links for Redsnow (Mac + Windows). Good luck guys. You can post some comments on my blog if you need more assistance. Thanks
yshuvo: thanks for you comment, but I did note there that before doing the jailbreak, Please back up your data.
mables: you will need to download the latest iOS version of your device. Please post comments to my blog so I can attend your problems much faster than here in QF. I am always online on my blog so much better post your issues there and I will guide you there in my site. here's the link http://www.macshared.com/. thanks
Cheers
