After seeing the image of Google selling the unlocked version of the Nexus One, I'm intrigued to buy one. However, I'm wondering if Google navigation will work without internet as I don't plan on buying a data plan. If Google navigation does work, can you tell me what features, if any, are lacking because of the loss of internet. I understand that this cannot answered by a person without a Nexus One, since its not released yet, but does anyone with a Motorola Milestone know the answer? Thanks!
