"Whilst I have my phone in my other side pocket, and my wallet in a back pocket."

I would say as a rule that world travelers do not put their wallets in their back pockets. I was in Barcelona for a few months and had close brushes with pickpockets trying to get my wallet in my FRONT pocket.

In my recent two-week cruise, to London, Amsterdam, Berlin, Helsinki, St. Petersburg, Tallinn, Stockholm and Copenhagen, there were serious pickpocket warnings for each city.

So, after my Palm Centro and keys and walllet, I don't have room for a Nokia anything in my pants pockets.
