You're certainly not getting the breaks, are you? Unlocking is relatively straightforward now that you've rooted.
Remember that Root Explorer app that I mentioned before? You can use that to make a copy of a certain system file, and open the copy on your computer (in a hexadecimal programme). There are certain characters to then look for, which are followed by your unlock code. It's then a simple matter of putting another network's SIM in your ACE & entering the unlock code when asked.
Let me know if you want full details.
