Let me leave my review on this:

It's pretty stable, slightly moreso than the last version, but this is still by no means the "perfect" build.
Remember to activate your phone with the Blackberry servers so it resyncs all your email accounts with your phone.

The good:
-Things seem to populate quicker, such as the list of pictures with thumbnail previews, the menu, etc.
-Still hangs when "too much is going on", but not as long as the last OS.


The bad:
-Still takes just over four minutes to fully restart, which is absolutely unacceptable. Yes, I timed it...
-STILL hangs. Constantly.

Other than that, everything is the exact same as the last OS. If they can fix the issue with the CONSTANT hanging and incredibly long hard reboot time, they would have a fully functional OS and great working OS.
