Update your Kindle now or get knocked offline

Older Kindles need a software update before Tuesday or they will lose connectivity

If you have a Kindle made before 2012, now is the time to dig it out of wherever it's stashed: if the software isn't updated before Tuesday 22 March, you'll be unable to take it online.

That means no syncing read states, no accessing the Kindle store and no buying new books - unless you remember to install the latest update. Kindles download and install updates automatically if they're connected to Wi-Fi, but if yours is lying unplugged somewhere, it has likely disconnected.
