Welcome to MMi,
I suggest you run redsn0w again to get rid of the error, and make sure you have the 2 bootloader files to do the unlock. 3.9 and 4.6 Here is a link that will have everything you need as well as instruction and links to all the files and firmware you need.
First of all you should use Firefox browser, works much better and more stable.
If the .ipsw restore file that you have downloaded has an extension of .zip right click on it and re-name it to .ipsw.
Download all files to your desk top so they are easier to find.
You may also have to change the way XP views files.
XP or Vista. you need to open "My Computer"
XP - go to the top menu and select options > Folder Options
Vista - Top left button that says Organize > Folder and Search Options
In that window you need to click the " VIEW " tab on top.
NEED TO SELECT “SHOW HIDDEN FILES AND FOLDERS "
Then unclick the option to " hide protected operating system files "
Once that's done click "apply" then ok and exit out of the window.
If you can not direct the download to your desk top for some reason.
Then go to this dir
users > "USERNAME" > appdata > roaming > apple computer > iTunes >
and the folder holding the downloaded file will be there.
You may have to reset your APN settings for your carrier. This is done in Settings/General/Network/ Cellular Data Network
APN settings can be found in a link in the top (Silver) of the page header under "Guides" Carrier APN settings.
