And the injector works great for those times I forget to leave GPS on when rebooting.

Thanks for your continued feedback - glad no issues have cropped up. There are some other features that we can implement (like automatic xtra.bin download requests originating in the gps engine itself), but with tytung's aGPS Injector working so well, I am very unmotivated to do so.
