I'm taking a trip to France in a little under two weeks, and would like some advice as to how to get my phone ready for the trip, in all aspects. What should I do for the actual phone part of the iPhone? I don't need phone services, just a handy iPod/camera with wifi. I was thinking I could just take out my SIM card, or always have the phone in Airplane Mode? For power, I'm going to need some type of converter. Anybody try this one? http://us.kensington.com/html/13926.html, or should I stick with apple's version, or an even cheaper ebay USB european charger? Thanks!
