BlackBerry Niagara 9630 OS 4.7.1 previewed: good mix of Storm and Bold features, OS 5.0 in disguise?

We know you're hungry for some more details on the BlackBerry Niagara 9630, so here we go. Crackberry's released the second part of its impressions with the device, this time focusing on the OS 4.7.1 that they note functions like a hybrid of the Storm's OS 4.7 and Bold / Curve 8900's OS 4.6. Features lovingly borrowed from the SurePress-equipped touchscreen include app switching by pushing down the menu key, trackball gestures in the photo gallery, a revised profiles menu, bubblier boxes in the options menu, and possibly a new memory manager within the media center. On their own, these all seem pretty minor, but they add up to a much more pleasant experience. Judging by the preview, it looks it's still shaping up to be one of the best 'berry's you can buy. The CB crew conjecture this might actually be the upcoming OS 5.0 in disguise, judging by their similarities. We'll find out for sure sometime in May, when we can get our hands on the phone and can check that version number ourselves.
