How To Use Your iPhone On Vacation (The Right Way!)

But the truth is that the iPhone 4 is such an amazing little computer that it can be actually useful on vacation -- both for technology and logistics and for taking and sharing photos and video.

This is not very secure, even if you use the iPhone's passcode unlock system. So you might consider an extra layer of protection, just as an app like Stash Pro. And remember to delete the photos when you get back, to boot.

Copy to cloud storage services

In addition -- or instead -- you might upload a copy to cloud storage services, just as Dropbox. This way you have a copy of the document accessible even if your phone gets stolen.
