I drank the Kool-Aid. I have joined the cult of the CrackBerry. Not once, but twice. An 8830 for personal and consulting use and a work-issued Pearl.
Where's the security implication, you ask? Well, there are a few of them which spring to mind. First, there's the temptation to use the thing while driving. Not just while driving, mind you- but while driving along Route 128. This is truly unsafe. The second is a real infosec risk, the risk of geeks with toys. What could it hurt to download random apps and run them on my 'Berry? Why worry about an SSH client from an unknown developer, what risk could that pose? I have a new toy, and I want to play. I have resisted the temptation to install any unknown apps (so far), but what about those weaker-willed geeks who succumb to the lure of tempting apps for their 'Berries? And then there is the whole data loss/leakage issue. I monitor five email accounts on my personal BlackBerry and another one on my work 'Berry- no chance to lose anything important there, eh?
What to do about it? My usual advice applies here- stop and think before you do something potentially inappropriate. Weigh the risks and act accordingly. Don't be afraid of the toys, but use them carefully.
And, no, I did not write this on the Berry while in traffic.
