And just to add my two cents on the unlocker:
- The download directory has copies of the unlocker apps, but they don't actually do anything without a purchase (Google Play or PayPro).
If someone installs one, it won't do much good without an actual purchase. This is not a hole in license validation, and does not rob anyone of what they've purchased.
- For those who've purchased the "pro" unlockers, installing a development build keeps existing activation. It's not necessary to update the unlocker at the same time.
- For those running the free version, installing a development build does not activate the app to full version.
