I just upgraded my phone to a new Samsung Galaxy S2 running Android 4.0.4, and I have been re-installing all my old apps. I set it up with the same google account as my old HTC Desire, and when I installed Winamp (which works fine, minus WiFi Sync - grr), it said I needed to purchase Winamp Pro, even though I already paid for it some time ago. All my other purchased apps work fine. What gives? Can anyone help me with this?
