I love the iPhone as a travel gadget – there are lots of very useful tools (and quite a number of rubbish tools as well) that you can download as apps. AOLTravel has looked into that and here is their list of the 11 best travel apps. One of the apps on the list this year is Gowalla , the app that allows you to check in at places when you travel, write something about them and build a sort of virtual passport as you go along. I think it is a fun app and you can see my profile on http://gowalla.com/users/gardkarlsen . I think Google MyMaps is probably the best travel tool on the iPhone but note that accessing the internet and using apps that require data traffic can be very, very expensive indeed (I experienced this in 5 minutes in Shanghai). The solution can be to buy a new sim card when you travel as that is normally not that expensive. What are your favorite travel apps?
