    Perfect timing! I did the first step earlier today and in a few hours I’ll try this step.

    Has anyone using the T-Mobile network in the U.S. had any luck with it?

      I did and its working 100%. keep in mind that you will not be able to access T-Mobiles 3G network but I have a work around… I bought 2 pre paid sims a $30 dollar a month pre paid T-Mobile card and a $30 a Month pre paid from AT&T. as well as a dual sim adapter that will allow me to carry both active sims in the phone simultaneously. under setting in the phone i I can now hit a button to switch between either T-Mobil and AT&T. Now i have both networks unlimited voice and text and 3000 meg of data per month for 60 dollars.
