Anyone used the iPhone on a long tour? Now it has maps, the LocateMe service, and of course unlimited data. You can even update your CrazyGuy tour via email, complete w/ photos from the iPhone.

However, I'm concerned w/ battery life. All that typing, uploading, plus the three hours of surfing I must do every day , will use up the battery very quickly.

Any suggestions for charging? A quick google didn't show anything useful.
