I've got an htc evo 3d that I'm gonna flash to verizon 50 dollar prepaid between now and my last post I've flashed quite a few phones and I'm gonna put a guide up on the how to do it. Right now I'm waiting on the mods to let me know if another guide I posted will be allowed to stay up. If not then check out xda between now and this weekend and you'll find a guide on flashing the evo 3d to verizon prepaid.
Here's a link to my youtube page
