Send a sms with the following sample contents to a Windows Mobile based device which has message preview enabled:
1. URL=http://www.google.de/">
2.
3. You know waht you can do with that, find your own...
- Tested on
HTC Touch Pro 2, Windows Mobile 6.5
Other devices from HTC are vulnerable too
- Solution
Disable the "Show Message" Option in the notification settings, or if the device is from HTC install the supplied patch for your device (which does the same).
