Roqy had provided BTGPS app (roqyBT4-1.0.2-1.deb, roqyBT4-1.0.3-1.deb) lately, but it did not work at my iPodTouch 3G (of course, iOS4.0.0 and I registered RoqyBT-license). I dunno why it did not so, roqyBT4 was certainly installed and it worked on its own, but any applications using a location couldn't use GPS location from roqyBT4.
Okay, it was fixed. I've found this. I tried to reactivate after deleting the License file(/User/Documents/roqyBT/License4), as a result, it worked. :-) (8th Sep. 2010, added)
