    I jail broke my Iphone 3GS last year using Spirit but am finding that I need to upgrade to at least OS4.0 to use some apps that I want.

    I have been reading about different upgrade options until my eyes are ready to bleed and think I am more confused now than before I started, lol.

    If someone could help me figure out my options I would greatly appreciate it!

    What options do I have for upgrading and jail breaking? I waited for a new Spirit release but it looks like that isn't coming...

    As far as I know 4.3 wont be released until March 11th so yes you can upgrade in iTunes. You can hook up your iPhone and click check for upgrade it will tell you the version and wont do the upgrade unless you accept it. So if it says 4.2 you'll be good to go. So do a backup and sync in iTunes before you begin then upgrade. If you're on Windows use Greenpois0n or if you're on a Mac you can either use pwnage tool or Greenpois0n the choice is yours. Once you upgrade it will remove your current JB so make sure you backup your JB stuff if you can.

    But wont updating from Itunes also update the phone baseband ? Since I'm running an unlocked 3.1.3 iphone 3gs, I would need to unlock again after jaibreaking 4.2.1. And what unlock do I need to use?

    OK You never said anything about unlock. Yes it will upgrade the baseband so you'll need to restore from a custom firmware made in pwnage tool. The Pwnage tool only works on Mac so if you don't have a Mac let me know and Ican make you an ipsw.
