I spent the past weekend in Paris and tried to save money by not relying on data roaming. There are some great application that work completely offline and I tried those during the trip. I worked with OffMaps to have street maps, Métro to know my way around, the Lonely Planet Paris City Guide, Stanza for reading and some helpers that already come with the iPhone.

Additionally of course I used the Memonic iPhone application to access my whole Memonic collection offline. I especially saved the hotel confirmation and tips for places to go to in Memonic and then access that information whenever it was necessary.

You can read more information for each of these apps on my personal blog.
