I'm thinking about buying the Hero through Sprint. I may be able to buy an unlocked version from Best Buy. If so, I'm considering not getting the data plan with my phone. I have access to Wifi 90% of my day and think it's silly to pay $60.00 extra a month to add data to our family plan just to get internet access the other 10% of the time. I'm curious how much this will limit my phone. Sure there are apps such as visual voice mail and Google Voice may not work well w/o an internet connection, but I would think many of the other features would work just fine. Any thoughts on this?
