Why is anyone actually signing this? The Zune 30 still has it and it's impossible for the Zune 4/8/80 to get it due to the lack of a hardware component.
Signing this isn't going to do anything. They can't institute a firmware update and just magically fix this (well, technically they could make a software EQ but that could create other issues).
This thread is just a waste of bits. It won't accomplish anything and you don't need an EQ anyway as it's worthless
