I have a fairly good travel routine down but one thing I haven't really perfected an easy way to have the places I going to be visiting (hotels, customers, places to eat, airports ,etc) easy to access via my iphone. What I do now is just punch it into my iphone as needed, not really a great method because I might be driving in a city I'm not familiar with or might not know the correct spelling etc.

For those that like to plan what is your pre-trip routine so that you have your destination readily available?
