Apple blocked the SAM method over a month ago...it was a loophole in there servers and they were able to block it without any IOS updates.

There is no way to unlock your iphone 4 unless you can call your carrier and have them unlock it. AT&T has unlocked a number of off contract phones for me (you need an account with them).

(you need an account with them).

Or you need to have had an account with them in the past.
