Outside of the sim card methods, it is impossible to unlock 3g iPhone as of now?

I hear that if your baseband is a certain number you can unlock via software otherwise you are out of luck. How can I view my baseband?

Settings>General>about>scroll to bottom.
Modem firmware indicates baseband version.

2.30.03

thats the unlucky one correct?

Yep. 2.28.00 is the latest baseband unlocked by Yellowsn0w.
