One of the major features of iOS 5 is the ability to update your iPhone, iPod touch, and iPad over the air. Today with the release of iOS 5 beta 4, Apple has released the first ever OTA update for iOS to developers. We figured we'd grab a screenshot and give you a look at the process. You simply check for updates in the Settings area, and when it finds one, you tell it to download it. The image above shows the download in progress. Once finished, you're asked if you want to install. A few minutes later, you're up and running again.
If you’ve got an HTC EVO 4G, you may wanna check for updates, as Sprint has started pushing out the first OTA (over the air) update to their 4G-enabled smartphone. System update 1.47.651.1 is 21.43MB in size, so we are guessing that it’s mostly meant to kill some bugs and optimize some things—but who knows, it may also unlock and enable the 802.11n antenna in the EVO 4G as well. If you get the upgrade, let us know what you find!
