    I've seen a couple people asking so I thought I would put the info out. If you need to unlock your iPhone don't upgrade to 4.2 via iTunes. This will upgrade your baseband. There are bundles available for pwnage tool 4.1.3 which allow you to create custom 4.2 firmware for iPhone 3G/s, and 4 while preserving your baseband. This is only available on Mac as pwnage tool is Mac only so if you have a Mac you're good to go, if you have Windows find a friend with a Mac to make you an ipsw. This will wipe your phone since you're loading custom firmware so make sure you backup and sync the phone before starting the process.

    Though you are ok if you have preserved your baseband throughout and use TinyUmbrella to keep it preserved. I am still at 1.59.00 and on 4.2.1 iOS.
