Yes.

Exactly. Right for these situations I think there is a necessary to make some modifications to the stock Gtk+ widgets. I think possible solutions include:
1) Use left/right arrows to navigate out the spin buttons;
2) or specify triple states for spin button:
	Non-focus state. In this state we could use any arrow key to navigate out from it;
	Focus without editing state. In this state we could also use any arrow key to navigate out from it;
	Focus and editing state. In this state we could not use arrow key to navigate out from it and it will treat arrow key input as manipulating its content.
	
	And we could use OK key in the phone keypad to switch spin button's different states.

It seems that we need to examine the Gtk+ widgets one by one to see if they could be navigated and manipulated by only using the phone keypad and then make some modifications accordingly.
