EDIT:: Nevermind I figured it out. Just compressed the folder into a zip and renamed it to .ipsw 
I feel retarded. But thanks for looking.::EDIT
I am going to jailbreak my phone, again, and upgradde to 2.2.1 from 2.2 cuz I figured It would be nice to have some apps that can only run on 2.2.1. But I need the 2.2.1 ipsw file. I have some links but it is a zip file and when I expand it it turns into a folder with a bunch of stuff like dmg files. I am wondering if I can jailbreak with this folder or is there something I am missing when expanding the zip. Is there some way to turn that zip file into the ipsw file I need?
Any responses will be greatly appreciated.
Thank you!!
