how do I install GPlay app on Pendo 7"

[ldfart]

The Pendo has 1Mobile for play store access, but an app I want to upgrade demands Play for access, I could prob root the device, but no guarantees. I'd rather not HAVE to replace it, just to have this one app work.

How do I rename the 1Mobile app to Play in Android 4.4.2? That may suffice for my purposes.
