Hello, I am now standing here trying to decide if to buy the iPad with or without 3G and my question is the following. I have already read here that I can use the tethering service (but it will drain the battery I know), but could I order a duplicate sim card and have 2 sim cards activated from Vodafone? Its probably the silliest question in the world and I assume IF it would be possible of course I would have to turn of the data plan on the iphone4 while using it on the iPad. The other option would be to swap the simcards but if I could have 2 and not have to swap that would be better of course... any thoughts?
