I choose the unlock team to unlock an HTC 8X phone.
Their price was attractive compared to other site, and after recording my phone IMEI, I've been confirmed they could unlock my phone.
Once I placed a P/O, I received shortly after an email saying they have not been able to process the unlock. They gave me some links to download softwares (which were for some scam) in order to unlock on my own, saying that if it did not work, they would refund me.
They NEVER did, even after 3 reminder e-mails they just ignored and never answered.
Stay away from them and rather consider cellunlocker.net which successfully unlock 3 phones.
