Just wondering - can you use the iPad 2 as a HotSpot the same way you can with an iPhone? It seems like you should be able to (3G, same iOS version, etc). It would make sense, but I suspect the answer is no. I'm going to the beach this summer (no Wifi access there). We'll bring my 3G iPad 2 and a Macbook. Ideally the Macbook could share the iPad's 3G connection. Any chance this is supported?
