Is it possible to connect a 3G wireless modem to the S7 Slim? It looks like it would certainly add that 'phone' type data access from wherever you are, so you could do things like navigate using the Google Maps app, or check weather and traffic conditions using apps like CoPilot (Yes, I'm using that I'm think I'm a little un-informed about the wireless modems. Can I assume it works something like a cell phone, with the same kind of wireless connection? How do you usually pay for the data service? Is it like a cell phone contract or pay-per-use (You have to buy minutes?) If I did get a wireless modem, I would probably only use it during the summer months for travel, so a long-term contract isn't appropriate for me.
