I am getting an iPad 2 as a gift. I already have the color and size determined(white 64 gb) and was wondering if getting the 3G model instead of the wifi model would be useful. I currently have an iPhone 3gs and will be upgrading when the next iPhone comes out. I can use the mobile hotspot feature on that. The only question I have about that is if I can use that on a month to month basis like the 3g data plan for the ipads(cancel the plan when I don't need it). If that's the case, then I might as well do that instead of getting the ipad with 3g. Do many of you have an iphone and ipad with 3g? If so, what's your reason behind doing that?
