Remember that sizable security hole that 9to5Mac found in iOS 5? They discovered that, by following five short steps, one could break into an iPad 2 by using a Smart Cover. This hole was expected to be patched in the next version of iOS, which released in a beta yesterday.
Shortly after the update released, 9to5Mac confirmed that iOS 5.0.1 fixed the security vulnerability that was active in the previous version of the mobile OS.
iOS 5.0.1 is scheduled to be made available to the public within a matter of weeks, bringing iPhone battery drain fixes and other improvements. Registered developers can download the update now to begin testing their applications.
