Ok, so I was at a family event and my 16 monther stole my phone from my purse. He figured out how to do the slide-to-unlock about a month ago. He's well on his way in technology. Case and point, his cousin and he had a playtime with my phone and now, I am without a working calendar. This probably had something to do with the fact that he is due for shots in august sometime. I tried replacing the apk and odex using root explorer from downloads online, installing them from other roms (I am using 2.2). I've even gone so far as placing them in the app folder and resetting the phone in hopes that somewhere these files would be picked up. I get a calendar, but not one capable of connecting to my google calendars, as most calendar apps require the stock app to lead them to these things. Maybe he deleted something else that is inhibiting this? I checked my list to this and see nothing amiss besides the bloaty metropcs things. I've done a pretty thorough investigation on this and perhaps I missed something but any help would be great! Thanks! P.S. I did circumvent the possibility of this ever happening again by actually setting a real lock on my phone.
