[Click Android Development] Aldarone:
I think this is due to a problem with the GPS. It's a bug from OpenEclair so it's present in that rom too.

I wonder if you (ikxdf) could fix that ?

Here is the output of logcat when I use foursquare with any Eclair ROM:

PS: Note that it is not exclusively foursquare, the output is very similar everytime I use a geolocation app (like Tellmewhere, or Twicca)
