I am new to Apple and the iPhone. I am heading out to the UAE in the next 2 weeks and I am looking for what I need to do to use my new iPhone 4 S in the UAE and Oman. I would like to use it for Internet, GPS when I am out, texting in the UEA and such. Not going to be using it for calls to or from the U.S. I just don't want it to useless on my trip.

Thanks
