What version of iOS is your phone at? The reason I ask is because if your not at the current version (4.3.3) the safest thing you can do is save your SHSH files first. This is the only way to revert back down from an upgrade if something was by chance to mess up. If your already at 4.3.3 don't worry about this as much. The program you will use to save these files is called TinyUmbrella. You won't need this program for the actual jailbreak though.

I'm still jailbroken on 4.2.1 and I don't want to update and possibly mess up my jailbreak and the installed packages. That's how much it's worth to me.
I used a pretty easy YouTube video that showed me how to do everything step by step. Surprisingly I didn't run into problems! now I'm trying to figure out what I can do with this thing! Thanks for the help.
