I couldn't find another option to unlock my phone, so I used this service. It was higher than I hoped (a little over $20), but I got the code within 5 minutes and it worked with my Motorola Defy (T-mobile to AT&T) on the first try. I don't know what the customer service is like, because I didn't need it. But they sounded very eager to help.
I was hesitant to use the site because the Web Of Trust rating was in the orange, but I've had no problems with the service and I'd recommend it.
