Sprint Telenav Cab

[alphasite]

I was using Telenav on my Mogul with a BT GPS. When the new ROM was released I downloaded the Telenav Tilt application so I could use the built-in GPS rather than the BT GPS. I've now changed plans and have Sprint Navigation included so I would like to switch back to the version of Telenav included with the new ROM but I don't have any idea how to do this short of a hard reset which I'd really like to avoid. Is there a way to expose the hidden rom? I remember doing this on my PPC6700 a while ago but I can't remember what program I used for it, and a search isn't turning anything up. I'm probably using the wrong search keywords.
