Apple hasn’t yet released its first point update to iOS 5, but when it does, you’ll be prepared to grab it without having to plug your device into your computer.
When word drops that an update has been released, all you need to do is open Settings, tap on General, and tap Software Update.
This causes your device to ping Apple’s servers, responding with a graphic showing the new update’s version number and brief release notes if one is available, along with an App Store-like install button.
