First, it was a few people who wanted to get work email on their personal iPhones so they could keep up with the office even if they weren't there. Then it was a couple of high level people who decided they'd get iPhones as their official company phone. Now you have stacks of them all over the place and people are starting to ask questions about managing this many devices and security policies and...urgh! What ARE you going to do about all of that?
Instead of the heart attack you're likely considering at the moment, let me make a different suggestion: Check out the new Mobile Device Management Primer from MacTech! First and foremost, this is a FREE resource. Really. Go get it. It's THAT simple. It's written by Russell Poucher, an Apple Certified Trainer and session chair for the upcoming MacTech MDM event.
If the primer isn't enough, or it's just enough to show you all the things that you didn't even realize you should be worried about, MacTech has announced an event called MacTech InDepth: Mobile Device Management. This will take place in San Francisco on December 7th. If you were a regular person, you'd have to pay full price, but you're not! You, dear reader, get to use the special TUAW deal and get $200 off an entire day of curated knowledge. Even more important than the sessions, you get to hang out with a bunch of other folks who also showed up to learn more about MDM, giving you the chance to attend my favorite part of any conference, the "hallway track." This part is the part no webinar or conference call can duplicate, the part where you get to chat with other people randomly over lunch or between sessions. I have attended conferences and learned at least as much from the hallway track as I have from the tracks themselves!
Whether you get to go to San Francisco or not, you should definitely check out the primer above and spend a little time with it, especially if you are just starting to look at iPhones in your IT environment. It's free! So go get it, and see if you have any free time in early December. I hear San Francisco is almost as lovely then as it is in January...
