Im not sure about the x10 but on my desire all i do to remove unwanted icons is to long press on those icons then drag them to the bin that appears at the bottom of the screen.

 

Yup same in X10, its the android basic.... long press and the little bin appears at the bottom of the screen, just drag and drop it in there.

 

If you're new to smartphones in general, I'd also advise reading the User guide that you can find on the main menu on your X10, alot of it is fairly basic, but there are some useful tips in there

 

I hated the fact that the phone only has a guide on the phone as I like to read and do at the same time and the guide forces you to read about what you want to do and then go out of it and back to the task you want to do.

 

Yeah although if I remember rightly the guide did have animations which were helpful, although I agree. I guess they're trying to cut down on the 'old skool' manuals and move ahead

 

There's a manual for DL on SE's homepage but I think it sucks.
