Ok so i got this phone a couple days ago, really good phone and all but im just wondering if anyone knows if there is just a "beep" for say a text message? So i can set the ringer for just a beep. And another thing which is really bugging me is that I have a headset and i usually have the phone in my pocket and walking around tlaking on the phone it tends to push buttons; turning it off. Is there a setting on it so that it will lock the buttons while im on the phone?
