SMS Vulnerability For GSM Phones

"Demonstrations at the Black Hat computer security conference revealed that smartphones based on iPhone OS, Android, and Windows Mobile are indeed vulnerable to hacking via SMS messages. Those aren't the only phones that are vulnerable, though, and security experts are working with mobile carriers and handset vendors to patch the problem."

It looks like a general security breach in how almost all phones handle SMS. I'll be curious to see what patch is necessary and how far back Microsoft and their partners will go to fix the problem. My guess is, WinMo 5 devices won't get any on-device fix. We'll see. Because it involves the way SMS messages are crafted, it is possible the network could be modified to detect and trap the messages rather than allowing them to make it to your phone.
