I like having the phone on the ring+vibrate mode like most users, so you can hear it when not near and to be able to notice it in the pocket while in a noisy environment, but on the ring+vibrate mode the phone does only one short vibrate before ringing (unlike my previous phones) and I usually don't notice it... is there any way to change it so that it keeps vibrating (like it does on vibrate only mode)?? Why won't it give us this basic option...
