All right, great. So I was probably just going to buy the Fuze off eBay, unlocked, and pop my sim card in. What features would I NOT be able to use if I didn't have the data package? I would like to be able to use the internet off of WiFi, and not be worried about accidentally using 3G. Also, I kow it has a built in GPS (as opposed to just using triangulation), do I need a data plan to use this, or is there a WinMo program that I can download that can take advantage of it? I know on my BJ2, which has a built-in GPS, I can use Google Maps Mobile, and the only data charges occur when it has to download the actual map pictures.
