What firmware and baseband are on the phone?

If your modem is 2.x.x, you can't unlock; you can't downgrade the baseband on an iphone4 either. You can still jb; go to iclarified.com.
If you haven't already, start saving your SHSH blobs with Tiny Umbrella. It'll help you in the future.

edit: Why don't you just pay the money to get the unlock from your carrier? If they authorize it, Apple will unlock your phone and you won't even have to jailbreak.

Since you need to Jailbreak first:

Then Unlock:

Check your baseband on your iPhone though, as only 1.59 can be unlocked. If you have 2.10 you'll need to wait to see if a future unlock becomes available.
