I have a paid gmail address, and a free one. I no longer use the paid one ($50/yr type). My android market purchases are set up with that paid email. How can I associate my purchased applications (many of them) with my other gmail address?
I would think, that if you dumped all your gmail and Android Market cache data, it might force you to log in with your user name again. Unfortunately, all the apps you downloaded, and maybe paid for, wont be associated with the new account.
