That's how it worked for me. When I upgraded to the dHarvey's Black Vista Rom (2.9) and initially checked it, it said Disabled. When I attempted to enable it, I found my speeds really dropping.

What a shame they imposed a 5GB cap...I never had an opportunity to use it as a replacement for my crappy dsl. Even so, I'm living in NYC, shouldn't I have a ridiculous Rev A speed?

EDIT: If yours came with it saying enabled (what ROM are you using?), I would recommend tethering and running a speed test prior to disabling. Repeat after disabling.
