Though the iOS 6.1 software update may have improved network connectivity for many users, the software isn’t without faults of its own as users are now reporting a number of new glitches that are showing up after they upgrade the firmware on their iPod Touch, iPhone, or iPad and iPad mini.
One of them relates to Microsoft’s Exchange ActiveSync for push email, calendars, and contacts and a second glitch has to do with the passcode security.
The Exchange bug is rather serious and Microsoft’s solution right now is to have IT administrators block iPhone users from using Exchange for push content. Apple says that it has identified the culprit of the problem and a new software update will be available soon to rectify this issue.
The bug means that iOS 6.1 devices are pinging Exchange servers more and inducing excessive traffic, which can cause servers to slow down and delay push for other devices as well. Microsoft suggests that IT departments either throttle iOS 6.1 devices or block them.
In a support document, Microsoft says: “When a user syncs a mailbox by using an iOS 6.1-based device, Microsoft Exchange Server 2010 Client Access server (CAS) and Mailbox (MBX) server resources are consumed, log growth becomes excessive, memory and CPU use may increase significantly, and server performance is affected.”
Other potential short-term fixes including removing the Exchange server settings and waiting 30 minutes before re-adding them to iOS 6.1 devices as well as powering off and on iOS 6.1 devices. A permanent fix is forthcoming, according to a report on CNET.
Various businesses that use Exchange for push email have noted severe slow downs with devices running iOS 6.1 trying to access the servers.
Passcode Security Bug
A second bug discovered with iOS 6.1 allows users to bypass the passcode lock and gain full access to the iPhone or iDevice. None of our editors here at GottaBeMobile has been able to replicate this problem, but according to a report on GSM Arena, the problem is there and does pose as a security risk. One user even made a video detailing how he’s able to bypass the passcode–or PIN lock–and gain access to his own iPhone.
Another issue noted in the past with the software update include faster than normal battery drain.
