But I fear the answer is you won't be using any APPROVED METHODS. As it is not APPROVED very few will help you since it often involves something called ROOTING and installing another version of Android.
It does void the warranty and you have only yourself for support.
Having written this, I did this to my nook color and it's now working fine. I suggest you decide how far you will go out on the limb.
I registered my phone (Samsung Epic 4G) with the Market. I now have an Android tablet (Coby Kyros 1024), but market will not download any tablet apps because they are not compatible with my phone (don't want them on my phone!!) and it will not let me add the tablet to my registered devices.
The app is Adobe Flash Player. I get the same response trying to download from the Adobe site--it apparently links with Market.
I can download the app to my WIN7 computer, but of course the computer can't use it.
