Apple has just released iOS 6 beta 4 as an over-the-air download a few minutes ago. We knew something was up when one of our readers alerted us that the Software Update feature was failing with an odd error message, and within a few minutes, beta 4 became available. This release comes a little over a seven weeks after the initial iOS 6 beta that was released during WWDC 2012, just over five weeks since iOS beta 2 was made available, and three weeks since beta 3 first arrived. If you're on an iPhone 4S the download 282 MB in size, while the beta 4 update on the new iPad weighs in at 291 MB. Check Software Update in your settings app to grab it now!
