Strangely, the GPS 'sort of' worked on my HTC 6800 with the original wm6.0 ROM. Once I updated it to 6.1 I haven't been able to get it to work since, and this patch is no exception. Just keeps complaining about not being able to find the GPS receiver.
I know 6.1 is *SUPPOSED* to be set up so that the GPS "just works" but it doesn't, and that is what annoys me
