I don't know if you're in the UK or US but in the UK some networks won't allow customers to stream videos using the 3g network they provide even though the customer may have 1gb of data.
I think you need an iPhone to watch movies because no matter how new your BB, it will under perform compared to iPhone.
The ONLY saving grace right now having a Bold 9930 is the great qwerty keyboard and BBM...other than that...the iphone 4S is leaps and bounds beyound a BlackBerry. And the ipad2 over the PlayBook? I can GET Bright House Cable AND Netflix on an ipad2. 'Nuff said.
