Had a fantastic experience with Unlockthatphone.com today. I bought a T-Mobile G2x outright on a pre-paid plan and they claimed to be able to unlock it for free. Well, a week later and it's not looking good for Tmo customer service, so I decide to say, "Screw it!" and look online for an unlock code.
I find Unlockthatphone.com which had the best price at $14.99. I email them up and tell them I need the code pronto! So I pay my fee and what happens a couple minutes later but I get the unlock code from T-Mobile! I promptly email the guys at UMP and ask for a refund, not even expecting one since they already put in the order.
Not only were the guys polite about it, but they sent me a refund in a few minutes.
I was referred to these guys through this site, and would totally recommend them. Thanks again! And the G2x... well, it ain't no Blackberry, but it's a decent phone!
