I was just given a Tmobile Gravity 2 Phone and I'd like to know if there is anyway to add a PIN # to lock the keypad while the Phone is on so no one can pick it up and click the 'unlock' button and use my phone without my permission. It does automatically go into a lock mode but all someone has to do is just click on 'unlock' then click 'ok' and the keypad will unlock for anyone . I was able to set a PIN # for when I turn it off and then when it is turned back on my PIN # has to be entered to use the phone, but having to keep turning it off and on all the time would be aggravating and time consuming. Does anyone know how to set a PIN # so keypad will lock while the phone is ON . All help is greatly appreciated .
