Remember to upgrade your Kindle from Amazon – there’s a new firmware upgrade available, taking the system to version 2.5.2 (24.3MB – you may want to transfer via USB…)Updates include:

1. PDF Pan and Zoom (finally) — you can zoom into small print!
2. Collections – to group books and documents by topic or type (not just purchase sequence, author etc)
3. Password protection – so that no-one snoops on your top secret documents
4. More font sizes, with better font clarity!
5. Twitter and Facebook integration… seriously? Perhaps for the US market… why invade this space, too?

Just be prepared for a *long* reboot period while the firmware installs…
