This week 7Digital confirmed that they will be powering the music store in BlackBerry App World. They already power the music store on the PlayBook and BlackBerry Smartphones so this is not a big reveal. On the other hand they are promising to build on certain BlackBerry features like social integration and recommendation engines (think BBM). 7Digital does very well with their API with both RIM and Samsung using them along with others. Jason also pointed out to me that 7Digital has updated their BlackBerry smartphone app to use their new branding.
