Autoiphoneunlocker.com Complaint - Do not buy their services....
This company is scam, they charge $30 for something is free and they customer support is terrible. I paid and then I found out that their software is free at www.blackra1n.com
I emailed them several times because after paying because the stay iPhone 3GS with 3.1.3 firmware can be unlocked does not work and no reply yet.
My suggestion: don't pay for something is free.
