Better safe than sorry
I'm expecting the latest version of Records to become available any day now. Here's a tip: whenever you're about to download an update for an app that contains vital data, it's a good idea to do a full backup of your device immediately beforehand. If anything goes wrong, you can do a full restore to get back to normal. There's no reason why anything should go wrong when installing the update, but where data is concerned it's better to be safe than sorry!
