If you own a BlackBerry Z30, Q10 or Q5, then your smartphone can suddenly do a neat little trick. The company's latest software update enables those devices to become FM radios, letting you stage an impromptu dance party without a data connection. Version 10.2.1 also brings a series of minor, but welcome, tweaks to the platform, including a new screen for answering calls, SMS groups, offline reading mode and picture passwords. The update is making its way to all BlackBerry 10 handsets from today, including the Porsche P'9982, for all you fancy-dans out there.

Update: BlackBerry hasn't publicly announced that BB 10.2.1-enabled Android APK installation from the file manager, so we've been waiting for an official confirmation before making it public. However, several of you have been in touch to say that this feature is working on your handsets.
