BlackBerry Messenger will be available to download on iPhone and Android smartphones from this weekend.

BBM was previously only available on BlackBerry phones but will now be available as a free download from the Android and iOS app stores.

Users will be able to see when their messages have been delivered and read, and share photos with friends - just like on a BlackBerry.

BlackBerry says BBM video calling will be added to the app soon.

BlackBerry faces tough competition from other messaging apps with similar features, like Apple's iMessage which launched in 2011.
