iPhone 3gs jailbreaking questions.

[LoMayoKicksU]

I have made this summary for my guide:

Run snowbreeze then drag ipsw.
Follow instructions

Run umbrella, save shsh then start tss server.
Minimize umbrella and leave it running.

SHIFT+CLICK restore in iTunes(this will prompt U to select that custom firmware u
made, and choose that and wait to Itunes do the magic!

Maximize umbrella and click onto kick device out the recovery.

Run redsnowrc12 instead of ultrasnow to install cydia.

DONE!!!!

QUESTIONS:
Should iTunes from the pc be running at the background too?

I am now trying to get bootroom info too because i realized that it is needed.

Please let me if there is anything else missing in my guide.
