Back in March, I was plied with advice about what to pack and what to leave at home when I left for my round-the-world trip. DO pack a money belt. DON'T take wads of notes with you. DO NOT take your iPhone. All words of well-meaning advice - and all entirely ignored.
Let me explain: I've never found money belts useful or necessary and I'd rather have ready cash to minimise withdrawals from dodgy ATMs (depending on where you are in the world, your card may not even fit in the slot). But what I really want to talk about is how ruddy useful my iPhone has proved on my travels - and why I'm glad I rejected all pleas to take my crappy old Nokia.
