While we are on this, is there a comprehensive guide on how to "theft-proof" your iPhone? Not in the sense of preventing the theft, but rather the fallout on all our various online service access.

Using the iPhone backup to setup a new phone is a good reminder every time that not half of the stuff comes back correctly..

I'm not sure you'd really need a guide. Just use the phone as a phone and pretend like it isn't a smartphone. Suddenly you are teleported back into 2005: physical credit cards, physical transit passes, online banking via a desktop website. It is still up to you what era you decide to live in technologically today.
