Well I just upgraded to pr 1.1 and guess what I am getting the same thing. Apps wont install...same thing about needing to uninstall a conflicting object and I click accept but after the download the app wont install. This is seriously annoying. I paid for two apps in a row but I cant install them????
I have never flashed my device or anything. I have never enabled developer mode and dont want to knowing that it didnt help this guy who has the exact same problem I have and also the fact that developer mode drains battery.
I have one question though dude whats the last app you installed?
