Tricking an app into thinking it was running on a newer or different model (e.g., porting a Bold-specific app to a Curve).

However, the ecosystem died slowly. In 2014, BlackBerry Limited began focusing entirely on BlackBerry 10 (and later, Android). By 2017, they announced the shutdown of legacy services.
