Delete Themes - Why you cant do this is beyond me
Add To Go To - Can you actually add anything to this. On my 6230 I had all my profiles and loads of other stuff in here
Auto Keypad Lock - On all recent Nokia phones. After x amount of time the keypad locks

Anything anyone else wants to add?

Just realised you CAN delete themes you have downloaded by pressing C. The delete option does not come up when options is selected.

Just noticed you cannot download all the tones which come with the phone. Does anyone know where they are located?

c:\system\sounds\digital\
as for the auto key lock u can just download a program that does that

Speed dialling - Assign Key 1 for voice mail button; once assigned Key 1 cannot be changed; the only way is to reset back to original phone setting meaning all customization will be gone
