I am getting my iphone today in the mail and have a quick question about hacking using this method:

http://www.hacktheiphone.com/iphone_...r_windows.html

On step 6 of the preliminary steps here: http://www.hacktheiphone.com/iphone_...g_windows.html

1.do I use the 1.0 ipsw file or the 1.02 because he says Note: do not place newer firmware files in this folder! Use the file from the link I have provided.

-----

2.How does this guide change if I want to update to 1.02 if the iphone I get today is an older firmware?

3.How does this guide change if my iphone is already 1.02?

thanks for everyone's help
