okay, I will admit that I'm a self-confessed "four square" app addict and this is how I first noticed this. I am currently unable to check in at any locations because the GPS on my Droid X does not seem to be registering new locations. I keep hitting refresh and it still lists me at the last working location, which is my home. I've even logged in and out of Four Square hoping that this would resolve my problem, to no avail. I then opened the "Maps" app that comes pre-installed with the Droid X and when I hit "my location" button it gives me a "your location is temporarily unavailable". same with the "latitude" feature that also comes pre-installed on the Droid X. the GPS feature is turned on. these problems started happening about 24 hours ago.
