just wondering if i swap out the "L" shaped pcb board in my droid x will that effect my esn. Basically my my original back light went out and i have tested multiple lcd screens to see if that was the problem but unfortunately its not. so i want to buy a used phone off ebay to swap out the boards. but im not sure if the ESN info is on that specific board. i dont want to put a board with a working backlight in my phone and then not be able to activate it on my account. any help at all will be greatly appreciated.
