Hi, I have the same problem. I ordered an unlock code for a 8100 from GSMPHONESOURCE (because I have read a lot of good reviews here), 2 weeks ago, and up to now I don´t have the code, and I don´t have any answer to the 5 emails I have sent and to the voicemail messages I have left. The phone number is always either out of service or nobody answers it. Is there any other way to contact them? They usually don´t answer emails? The only email I have ever got was a payment confirmation from Paypal.
