If you live near me, I'll trade ya! 3.2 firmware is out on amazon right now, it is not compiled, if you can get someone to compile it for you, you may be able to have the ads. 3.2 is the version that comes with the Special Offers. Also, log into your amazon account on your pc browser, and go to Your Account, Manage Your Kindle.

That link may send you directly there.
On my screen, I have a Special Offers tab that says Enabled Yes. I can't turn it off, but maybe you can turn it on? May have to wait for the official 3.2 for the other kindles to use that.
