Epic 4G, set to allow non-market apps, rooted, stock rom. Purchased app Roam Control from store. Next day I know there's an update and check downloaded apps. Not there. Check in regular market, not there. Uninstall app and get refund notice. Still not there. I go to http:// androidforums.com/ application- announcements/ 162379-app-roam- control.htm and got the QR code using QuickMark. I get the website list and source data. If I click to launch in Quickmark, I immediately get "location can't be found." If I try AppBrain I see the app but when I click install I still get "Not Found The requested item is unavailable." Other apps seem fine and others seem able to install. Made backup, did hard reset, same thing. Any help?
