How do I update my iPhone 3G firmware but not to the latest version?

I currently am running 3.1 but would like to update it to the 4.1 version (not the latest 4.3 version). How do I do this? I have already gone online and downloaded the 4.1 firmware for iPhone 3G but not sure how to install it. I unzipped the file then tried to do the Shift>Update trick but none of the downloaded files could be selected. Am I doing something wrong?

iPhone 3G, iOS 3.1

There is no official way to do what you want, that's why the files can't be selected. iOS 4.2.1 is the last officially signed firmware available for your phone. If you want to install any other firmware you'll have to go elsewhere for instructions as such cannot be discussed here, per this forum's terms of use, sorry.
