my phone lost an app?

[markinnh]

On my droid bionic it came with VZ navigator , I had it on another phone and hated it but this phone also came with another app called navigator ( I think)
the app was on my screen with a small blue tear drop and nothing more. It worked great and one day it just was not there any more. Anyone have any idea what its called and can I re load it? If you know please email me at [email protected] Thank You, Mark

I figured it out, its not a teardrop its an arrow and somehow it dissapeared off my desk top but was still hiding in the phone. This app is probably the most used app on my phone. I think its called google maps?
