From the Beta Labs blog post:
The new version contains more extensive set of tests to help you to figure out where the problem may be. New version also contains the advanced mode functionality for techie users and possibility to run all tests or all subcategory of tests. The look and feel has also been improved. The new version contains the following tests:
- Vibrating alert
- Memory
- Battery charger
- Memory card
- Cameras
- Keypad
- Screen
- USB cable
- Web browser
- Network coverage
- Data coverage
- GPS
- Earpiece
- Microphone
- Loudspeaker
- Headset
Of course, most 'techies' can tell from basic use what most problems stem from, but there are now some genuinely useful tests in this suite and I can't wait to exercise our new Symbian^3 phones when the relevant update is made available.
