An iPhone and a BlackBerry Z10

You might have heard that the recent iOS 6.1 update has been causing quite a few headaches for corporate users. One issue causes a heavy load on the Exchange server, which ultimately locks up mobile access to e-mail. 

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.

This results in end-users getting an error message saying "Cannot Get Mail - The connection to the server failed." The cause? Apparently this bug has to do with responding to an exception to a recurring calendar event. 

That's not the only issue with iOS 6.1. There's also a glaring passcode bug that allows users to bypass an iPhone's lock screen and get right into the call log and address book.  

As we're all well aware, BlackBerry can handle calendar events just dandy, and BlackBerry 10 specifically is built to play nice with Exchange ActiveSync. Plus I don't think any of us have ever been worried about our lock screens being bypassed. There's been a lot of talk about iOS grabbing enterprise market share, but with issues like this, it's easy to see why IT admins might rather issue BlackBerry devices.  

Those of you working in a corporate environment, have you noticed your iPhone-toting colleagues having issues?
