iOS 7 officially launches today (which is to say tomorrow, thanks to that pesky international dateline), and if previous launches are any indication, it’ll be quickly adopted by the Apple faithful. Before you leap in, though, there’s one thing you absolutely must do.
Backup. No, wake up in the back there, because this is important.
I don’t care if you backup to iCloud or use a cable to backup via iTunes to your computer. Frankly, doing both would be wise. If Apple’s dotted all the ones and crossed all the zeroes, the upgrade process to iOS 7 should be seamless for most users, but there are always edge cases.
This is true, too, of upgrades for other operating systems; I’ve had Android upgrades and Windows Phone upgrades die on me, taking phone contents with them. Backup is boring, but backup is sensible.
You may not be one of the edge cases, but if you are, having a backup — which should only take a few minutes — will ensure that you actually don’t lose all that much beyond having to go through the upgrade process again. Not having a backup is a swift way to kiss your data goodbye.
