How does Android.Play know my device config?

[AngelOfGrief]

Hi,

I have an Android device with ext. GPS (meaning PL2303 via USB + USBGPS4Droid software running). Whenever I try to get GPS enabled software off market, I don't get shown any, because market (Google.Play sorry!) thinks my device does not have a GPS receiver.

How do I change the settings to make it believe I have GPS? Which file holds these settings? Device is rooted, naturally, I can access any dir/file via SSH.

Thanks!
