I decided to use GSMLiberty based on positive reviews I saw on Internet. The phone is a Samsung Galaxy Mini purchased March 2012 locked to "3" mobile phone provider in London. I received the unlock code from GSMLiberty in less than 15 minutes, and it worked perfectly on the first try. I was able immediately to make a call using a USA ATT SIM card. Also was able to use the Galaxy Mini as a wi-fi hotspot with the ATT SIM. Top marks to GSMLiberty!
