    Nope, there are SIM unlocking tools, but most are garbage and hardly work.
    Try downgrading the baseband to 2.28.00 for Yellowsn0w to work by getting 3G Fuzzyband Downgrader from Cydia.
    Note: this only works on iPhones with the 5.08 bootloader, so don't be surprised if you aren't successful.
