BBM OS 7 Update today (Bold 9900)

I just updated BBM for my 9900 and lots of different elements appeared

1) PlatformDemo
2) PlatformDemo2
3) BBM SDK Demo
4) Begging Demo

Not wishing to appear stupid :huh: but what do they all do and can I just delete them without affecting the functionality of the installed BBM app?

Thanks

I too updated and have tictactoe and tictactoe2 now on my device. Upon starting these they ask to connect to BBM. Does anyone have insight to these? Valued? Bloatware? Thx
