[SOLUTION][FAQ] Why is my (insert system app here) gone?
Where is x system app?
If you are running the stock ROM that comes with the phone (rooted or not), then the disappearance of system apps is a bug with the stock firmware that comes with this phone.
Why is it gone?
Sometimes when you remove apps from the "menu/applications/manage applications" menu in settings, a plethora of system apps are deleted. You probably just noticed the one that caused you to make a thread about it. If you go back into the manage applications menu, you will probably see that many other systems apps are greyed out, including calculator, google services framework, and others. It is unknown why this happens when removing apps from that menu, it is just an annoying bug.
How do I fix it?
Well, there are two solutions. One, very simple, is a factory reset, and everything will be fixed. However, you will lose all your apps and data if you aren't rooted. The other solution, the way I chose to go after this happened to me 3 times, is to root and load any other custom ROM, I chose Incredible 2 HD.
I hope this thread helps answer people's questions. I have been seeing a lot of posts on this lately and wanted to provide a complete answer for people all in one place.
