It got easier. Penetrated, completely compromised; the hack validated by Steve Bellovin and Avi Rubin; published in the NYT; and even slashdotted. On the plus side the guy that hacked it is a former employee of the NSA.
So, if you carry a computer in your pocket, it's as vulnerable as a computer on your desk. Not that big a surprise. (And I've got my iPhone sync'd up nicely now with my (OS X) computers, so they all have the same data and the same risk.)
I'm not surprised - generally speaking, security is inversely related to complexity, or at least, it takes more effort to make a complex system secure than a simple one. As mobiles do more and more they will be less secure, unless there's proportionally more effort spent to clean things up. Is that happening? I don't see it. There's probably been less time securing your data than was spent making sure AT&T gets paid for ringtone downloads.
Also, probably your iPhone is less secure than your OS X machine at work, tho, because you have less control over your iPhone (at least, unless you're going to go to the work of hacking into it).
