I am going to be going to hawaii shortly for my wedding. We are going to do a week on Oahu and than a week on an island hopper cruise. Are there any Hawaii users out there and any thoughts on using the iPhone on the islands? Are there alot of dead spots or places with just horrible reception? How often are you on edge? Also, I have never flown with the iPhone, do I just turn it on to airplane mode and I am good to go? Any info would be great. Thanks!!
