will make you phone silent and using the one that was designed for the Mogul won't work either.. so here is an updated version that works for this new ROM
enjoy... it goes from normal to VERY HIGH on Vol 5!!!! this has only been tested working on an 6.1 rom that was created by JD using the alltel rom and it SHOULD work on winmo 6.0 please post your results here.
***WARNING*** This will make your earpiece and speakerphone REALLY LOUD!!!!!!! I will not be responsible if you damage your speaker while using this********
