I'm new here so please be patient while I catch up.

I'm about to buy an unlocked 650 and am looking at flip cases. It would be nice to get a case that didn't requie opening when I'm on the phone - but I think there's a problem with that.

When the phone rings, can I answer it by pressing the "side button"? And when I'm finished with the call, can I hang up by pressing the same button?

In other words, can the phone be used WITHOUT opening a flip case (assuming the case has holes for the mic and ear piece)?

I've looked through the instruction pdf and can't find this answer.

Thanks,

Norman
