Ok...so if I understand correctly you can get on 3G three ways with the iPad 2. 1) Buy the WiFi + 3G model for more money and access/buy a Data Plan for it. 2) Buy the WiFi model for cheaper and a mobile hotspot thing from Verizon and access/buy a Data plan and use not only your iPad 2 on it...but you're laptop also. 3) Buy the Wifi model and have a Verizon iPhone...do the mobile hotspot through the phone and sync the iPad through the iPhone. Which way works the best? Which way cost the cheapest?
