In case you haven’t heard this story already, a prototype phone with Windows Mobile 6.5 was stolen last week at the Mobile World Congress, Information Week reports about it here. The device was used by a customer to do a demo and it got stolen. Except for his personal data on the phone there was of course also a risk of someone getting access to the bits. But what Microsoft did was just wiping the device remotely so both OS and data was erased.
Pretty good example on how important it is to have secure mobile phones! More about Windows mobile here
