    If you have a mac, you should use pwnage tool, and that will let you update to 2.2.1 without the baseband update and still run yellowsn0w. Or if you have windows you can search on google for a pwned 2.2.1 firmware without the baseband update, download that, and option-restore in itunes to that 2.2.1 custom file. :D

    Your contacts will sync back on after updating to 2.2/2.2.1.

    Take both the T-Mobile SIM and the Gevey SIM tool out.
