I'm not really sure what I've done or how to fix it, so I am hoping someone around here can help me out. I have a rooted Droid. I was clearing out the default apps that I don't need yesterday, and I saw "mms.apk". I assumed it was only the default messaging app. Since I have handcent, I just moved it to my SD card. That is when the problems began. When I get a text message now, I can still see it in my status bar, and if I have popup enabled in Handcent, it will show there as well. If I open up the program, though, it shows absolutely nothing incoming. It will display my outgoing texts (which work fine), but no incoming texts, contacts, pictures, nothing. I tried to fix it by simply reversing what I had done... I moved the app back to system/app where it was. It made no difference. The default messaging program wouldn't show up in my app menu either. So... I tried installing it. "Installation not successful". Where do I go from here?
