Ok I have done this a couple of times, and it has worked great, but every time there is an update it seems to get more confusing. I have a first gen iphone that I have unlocked and use on T-mobile, it currently has firmware 2.1, I would like to update it to 2.2.1, but I am a little confused. I am using a Mac to do this for the first time, every other time I have used a windows machine. Can I just download Quickpwn follow the instructions on iClarified, and be done? Are there any problems or bugs in 2.2.1? I do not want change the boot logos, how do I keep from doing that? Would it be better to use the pwnage tool? Anything else I should know or keep in mind when doing this? I know there are stickied threads for this stuff, but like I said after all of these updates it is really confusing to try and figure out what it is talking about where haha. Thanks for all the help you can give me!
