I’m still getting better at using my iPhone for preparing for upcoming trips. (Later this week I will travel to Perth, Australia for Christmas, with a stop in Tokyo on the way there).
I’m also trying to rely less on getting a local cell phone signal, to pull up the information that I need. So I have made sure I see my flights and hotel stays in airplane mode on my Google calendar, and made a calendar-view paper print-out to boot. I have also put the apps I will use in one place, and even created flight reservation and hotel details as ‘pictures’, and put those in an off-line photo album folder.
