I have an Evo 3D. And I checked Verizon's coverage map and they totally sweep over my neighborhood with their 3G voice and data. On Sprint I fluctuate between two bars and none in my neighborhood. Can I make my phone use Verizon? I heard about custom PRLs that can do that, do I need to be rooted to use them? Are there PRLs that let me switch between Sprint and Verizon at will on my phone?
