Audio Adapter not working
 

I just got my mogul last week and it came with the 3.35 rom. It included 2 adapters in the box - 1 for power/synch - factory earbuds and 1 for power/synch - 2.5 headphones. The one with the 2.5 jack does not work - is this because of the rom? Odd that they would include an adapter that does not work with the mogul.
