Ok heres the Deal with Straight talk and boost they DO NOT USE the Verizon NETWORK... for anything.. they run Sprint for Android phones. there is software available for flashing HTC,Motorola,Samsung,LG and so on available at
YourCellular.Net for 24.95 they give you 1 months access to all the downloads on their server. Allowing you to Download as many Flashing utils as u need for almost every CDMA Phone made. once you have the proper .zip file or whatever it is and drivers for your phone READ THE INSTRUCTIONS so as not to brick your phone.. I have done this on 4 EVO 4g's and 2 3D's all work fine on 3g network... Hope this Helps...
