Not sure if it's a scam, I've ordered unlock my iphone 3 days ago from mobileunlocks.com but it's still in process. The website says the process will take 1-24 hours when I order it. I have emailed them yesterday asking for refund but haven't got any response. I've just emailed them again. Be careful with website. And another tricky thing is that when you choose unlock phone button, you will be given status check order instead of Unlock.
