I just bought a N900, and I love it. As a Linux user with Ubuntu on my home machine, I love the terminal, and the openness of the system. The only think that the N900 hasn't satisfied on my smartphone wishlist, (made before seeing the N900) besides multi-touch, is the GPS. I know it has one, but I cant get it to work. I do not have any sim card or plan, as my wallet is still recovering. The N900 is working fine without it, but do I need a sim card to use the GPS? I have left it outside where it should get good reception, and connected to a wifi network as was mentioned earlier by Torpedo48: and all it did was say "searching." Not too important, though it would have helped me from messing up my directions today. (I probably would have wrecked the car, looking at it though.) Any help, or enlightenment would be helpful. Question: Do I need a sim card/data plan to get the GPS to work, and if not, what is required? Wild_Doogy
