I'm thinking of getting one of these someday for games on my phone, especially stuff that calls for more solid controls. Anyone know if these work with Graal?

Really not a big fan of touch screen buttons.  

Not sure, you could probably make a hack for it though.

Also, they do make joysticks for iPhone that you pop onto your screen and it sticks there, then you move it around (joystick) and it touches the screen for you. Not bluetooth and not powered at all. I do have one and can confirm it mostly works. Although sometimes if you move the joystick too hard, it'll fall off the screen and you will have to reattach it to place.  

Sounds strange, the attachment. It would be nice if they added a bluetooth joypad option if they didn't.  

There are controllers for iphone and they work with graal.
Like the logitech powershell.
If you jailbreak your idevice you can play with a ps3 controller and some other stuff  

I use android.
