Curious how to update to iOS 5.0.1 — or any future iOS update — over-the-air (OTA) directly on your iPhone, iPad, or iPod touch? Yes, Apple finally pulled the big test switch in the cloud and you can go from beta 3 to beta 4 via a svelte, under 200mb, bit differential (delta) update-in-place rather than the usual beefy 700MB+ iTunes restore of updates past. We’ll show you how, after the break!
Initiating an OTA update for iOS is really easy. You might see a red notification badge on your Settings app to alert you to an update, or get a popup notification telling you it’s ready to install, but you can always check on your own, at any time.
Not only does iOS 5 update OTA, it updates in place using bit-differential (delta) files, so you should get a faster, much more efficient process. For example, there’s no need to restore from backup afterwards or re-download your stuff.
Seriously, once the download finishes it’s amazing quick and smooth. Apple may not have invented OTA updates (Chris swears BlackBerry has had them for ages, and Nokia likely invented them in 1812…) but if this is any indication, they’re doing them right.
