Is www.gsmfast.net reliable for T-Mobile USA iPhone factory unlocking?

[Fruck]

I need to factory unlock my T-Mobile USA iPhone 4s and I couldn't really find anybody else providing that service for such great price but http://www.gsmfast.net/
Anybody has already tried them out? They look legit and all, but I would love to hear their customers.

Would really appreciate any kind of feedback!

Thank you!

Hey!

I would definitely vouch for http://www.gsmfast.net/ as mine iPhone 3 was unlocked within 12 HOURS! and it was no hassle. I had couple of concerns before I made my purchase like whether they would issue a refund if they are unsuccessful or whatever and got positive response but didn't even have to disappoint since they delivered what they promised. So no worries, just go ahead with them and then come back and share the experience yourself!
