As soon as Apple updated iOS to versions 7.0.6 and 6.1.6 to fix an SSL vulnerability, TUAW let you know about it. Apparently some people still haven't updated, and app-enabled bank Simple has sent out a tersely-worded reminder to its customers letting them know that if they don't update before Monday morning, they'll be unable to sign into Simple.
Although updating is a good thing for any iOS user, it's critical for those who are using banking apps like Simple. As the company notes, "Why the drastic measures? A security flaw was recently found in older versions of iOS, and if your network were compromised (say on a public wifi hotspot), it could expose any data you send. Updating iOS fixes that vulnerability. This measure is part of our ongoing commitment to protecting your banking information."
The company also provided the simple steps for performing the update, which we repeat here: "It's easy to update your iOS: tap Settings > General > Software Update > Download and Install. You must be connected to a wifi network in order to download and install the update."
If you haven't yet updated to either iOS 7.0.6 or 6.1.6 on your iOS devices, or run the OS X Updater for your Mac, please do so as soon as possible. And if you're not familiar with Simple, be sure to take a look at our review of the service and app.
