Two questions:

Do you have to root the phone first before using any of the unlock methods?

If I want to put a bigger microSD card in, can I just copy the supplied 2 gig card files onto the larger card (incl. apps I put on the original card) or do I have to re-install apps fresh on the new card?

Thanks.

From the posted site, I think you can just copy the data from sd card to sd card.

I bricked my Gio on Win 7 x86. I did note down the unlock code and at the end I also executed the unmount command. I tried reflashing a couple of times in the download mode. Now it refuses to go into the download mode, all I see is a blinking black screen. Gotta fix this bugger...Any thoughts? Maybe I should try Linux..
Did you use "unmount" (incorrect) or "umount" ?

Does anyone know how to backup the /efs folder and other important system folders before attempting to network unlock it?

http://forum.xda-developers.com/showthread.php?t=859914 <- I'd imagine the steps would look like what's done in this thread. You'll have to tweak the commands a bit though since that was for Galaxy S. Although I personally don't have too much guts trying that method.. haha.. "rm -rf" command can get fairly catastrophic..

To everyone who successfully unlocked their phone using psyfactor's method, did you guys reboot your phone after the umount command before inserting a non-Bell sim to enter unlock code?

Thanks, I already tried the first command in this thread because thats all I found too regarding backing up of /efs
when I entered "tar zcvf /sdcard/efs-backup.tar.gz /efs" I got an error that said something like "directory doesnt exist" or "cannot be created" so I didnt go any further. I even tried some basic linux commands to look around the file structure but I couldnt find an obvious place of where /efs is stored.

With all these Gio's being soft bricked (including the last one that I've tried to unlock), it would be a good idea to have a backup plan ;)

I did. I in fact I ran the phone for a day with a Bell sim before I put a 3rd party sim in, as I didn't have one to use. Funny enough it was a Mike (Telus) sim that I inserted as my in-law was visiting and we live waay outside their coverage area. As soon as I turned the phone on it asked for the unlock code.

Here is your problem:
It is umount; NOT unmount

I am sure many people who bricked their Gio's because of that.

After you get the code, do you press ENTER on the terminal screen or just delete the information that spits out from perso.txt BEFORE you use the umount /efs command? Do you stay in SU mode or exit out of that as well before reboot?

If you read the posts, it is "follow the instructions to the letter"

So to answer your question, stay there and issue the next command (at least that's what I did)

So, I performed psyfactor's steps using method two. I quadruple checked everything before entering each command. At the final step, I performed the umount command and hit enter and the cursor went to the next line. I wasn't sure if something was supposed to happen so I performed the command again only this time it said failed. I figured it was simply because umount worked fine the first time I executed it.

After rebooting the phone with my rogers sim card, the phone booted up just fine. However, it didn't ask me to enter an unlock code like the instructions indicated. I then figured I would try and reboot the phone again and hopefully it would prompt me for an unlock code. Now the phone keeps flashing the black Samsung screen. I can't get back into terminal though it seems I can get it into emergency download mode. Please help... :(
