First of all check the firmware... If its not 4.xx.xx then you will be best to restore to 3.0 firmware.. This will update your baseband to 4.26.08, then as suggested above, download 3.1.2 ipsw, use Pwnage to create custom IPSW - this will prevent baseband being updated to 5.11.07 which can NOT be unlocked - once you are on jailbroken custom 3.1.2 with 4.26.08 install UltraSn0w and jobs done...
I´ve jsut done exaclty this on my 3G which was 2.01, the least hassle method was to go standard 3.0 then custom route...

Techinically no, you could just use an old version of YellowSn0w, but I´d recommend standard restore to 3.0 so you do get a new baseband (Do not go to 3.1 or you WILL LOSE UNLOCK)....
Also UltraSn0w (unlock for 4.26.08) is prooving more successful than the previous yellowsn0w...

No, update to 3.0 normally, download the official 3.0 ipsw (http://appldnld.apple.com.edgesuite...090617.VfgtU/iPhone1,2_3.0_7A341_Restore.ipsw)
Save it to your desktop then in iTunes Option+Restore... This will present you with a window to select the IPSW... Navigate to your desktop where the 3.0ipsw is...
Let it restore and when finished repeat but with your custom 3.1.2 IPSW.. this will leave you with 3.1.2 but Baseband 4.26.08 which you can then Ultrasn0w and use any sim in...
