According to people on TJC, you don't need to reflash to see the proprietory stuff in the Jolla Store.

As for the Android Support, again according to someone on TJC, it says it's only available to CBeta users right now.

However, I wonder if it's locked to a newer release. The current release is 3.0.0.8, whist the latest available (via CLI [1]) is 3.0.0.11. Perhaps this might work?
