Screen capture showing download of iOS 7.0.6, which patches security flaw.

Just read a news article on a serious security flaw in iOS 7 and immediately downloaded a software update to my device to patch this problem.
According to the news story linked above: “If attackers have access to a mobile user’s network, such as by sharing the same unsecured wireless service offered by a restaurant, they could see or alter exchanges between the user and protected sites such as Gmail and Facebook. Governments with access to telecom carrier data could do the same.”
I had to invoke the update process manually by going to Settings > General > Software Update where I was invited to download the patch, iOS version 7.0.6.
Those among you with iDevices might want to think about doing the same.
