The Research In Motion BlackBerry Storm successor the BlackBerry Storm 2 has now been given a preview by the guys over at phone arena, and they say the BlackBerry Storm 2 9550 will more than likely be the first unit to run 5.0 software.
They state that functionality wise there is nothing new but the biggest change they saw was threaded text messages. Furthermore menu transitions are now animated but overall it is like the change from 4.5 to 4.6/7.
The BlackBerry Storm 2 they had was a pre-production model and several time the handset just simply restarted itself with no reason which RIM needs to work on, but in general the responsiveness of the handset was good. We have a video preview for your viewing pleasure below.
