what hardware button presses reboot the Imagio?

[mlevin77]

I'm using the stock Verizon ROM. I've got apps that reboot the phone; that's fine but every once in a while, the screen is stuck and I can't activate them. Is there a button combo (e.g., hold down the red and green buttons on the front or something like that) which reboots the device without having to take the back cover off? I read a few posts on-line where people say there's no such thing for the Imagio, but I could have sworn I did it by accident once. Today I took it off the charger and the screen wouldn't turn on at all. I tried holding down red and green and got a screen I've never seen before: all white, it says "Data dump" or something like that and at the bottom a bar that says "serial". I had to take the back cover off and reset that way. Is there a way to reset from the buttons on the front?
