Now you have totally lost me...
lol
The themes are the main thing. I put two on and now stuck with them. LUCKILY they are quite good!
Ok maybe I wasnt clear enough...?
If you enable say caller name when someone in your phonebook rings you, the ringtone fades in and out with a robotic voice saying their name.
Themes wise, you should be able to remove 3rd party themes from the application manager.
