Jailbreaking a new 2.2.1 iphone

[jamesapp]

A couple of days ago I got a new 3g iPhone from an apple store. My old iPhones wifi stopped working so I restored my iPhone and brought it into an apple store and they removed my sim from my old iPhone and gave me a new phone. I want to jailbreak my new phone, my new iPhone is running 2.2.1. I have quickpwn on my laptop which I used to jailbreak my old iPhone when I updated to 2.2.1. My question is, is there anything I should be concerned about jailbreaking my new iPhone?

If you cant follow directions, be afraid...VERY afraid.
