Hi I have a treo 650 and I was wondering it there was an app out there that will allow me to have my phone totally locked when its locked...For example, when I lock my phone via security and someone calls me, the name and number still pops up...The same thing happens when I receive a text....I just want to know if there is anything I can do to block that, b/c I am around alot of nosy people at home and workplace....Thanks in advance
