so my palm pre + developed a fun crack starting from the bottom right corner then into the top middle.

Now i ended up removing my old Pre screen and put all of the fun guts that were in the Pre+. Now i do have internet connection (though it only says EV) and on the top left it is claiming that Verizon Wireless is my carrier. However, when i look into my device info it is saying that its configuration is Sprint 2.3 and in advanced, it is saying my carrier is Sprint.

I, most likely, didn't put my odd make up of the two devices correctly, is there something I completely missed?

Any sites that you could recommend letting me understand what each little piece of hardware does/is? I am a bit slow so having visuals would be superb
