Alright.. well I upgraded to this OS while at my workstation PC at my office.
Happy to say that I went through the install process seamlessly.
There were no snags.
I went about my normal day while the upgrade was running,
and expected a 40 - 60 minute upgrade due to the amount of data my BB holds at any given time.
Backup, upgrade/install, and reload of the backup occurred in about 30-40 minutes.
I was having keyboard issues the couple days prior to the upgrade
(which is why I did the upgrade so soon), and I'm happy to report that it cured my issue, as well as very happy with the new text layout (not really layout, but highlight of whole word in SureType, the top display).
I do have a couple of snags so far regarding OS.
I text and email A LOT.
I have my settings to display the last 15 SMS messages when I open and reply to one.
75% of the time, the first SMS in the history (which should have been the last transmission, either in or out), shows up as the second to last, or even third and fourth last message.
Really quite irritating when I rely on the history feature to recall what I'm replying to.
Other than that, I use the Phantom theme, and once in a while, after a new SMS or email comes in, and the first portion of the text shows up on screen and highlights red, I'll read it, and the screen returns to grey, but the portion of the text never leaves the screen.
But, that's my only bug.
Very happy with the smoothness and operability of the OS so far.
Mucho better than the .73 I upgraded from.
