Upgraded from the prior 8830 beta. Stability seems a little better, for me.
One major change: with the prior beta, there was a "default" calendar that was separate from any of my e-mail accounts. A sync with DM would sync only with this "default" account. Which meant that any invites I would receive would be duplicated on my calendar (once for
and another for "default").
For 77, the default calendar is tied to one of my e-mail account. However, it was set to my blackberry.net account, so every one of my calendar entries appears twice: once for blackberry.net and once for my work e-mail.
I had to delete my calendar database and re-sync (after setting the default calendar, in options, to my work e-mail).
So, despite the mess that it caused, I'm now happier.
I'm happy to see the return of the folder icons.
As for the issue of missing ringtones... what a pain! All of my profiles were reset and I had to fix them all.
As for fixing this: I have no jl_cmdr folder. I do have a JAVA folder, however, I put the file from the prior beta in there, renamed from qualcomm to 8830, and re-ran install manager in DM. Worked like a charm to get the file on my device.
It reset my e-mail profiles to not prompt me on delete (see VHT's post).
This was the least smooth "upgrade" I've performed.
Be aware that it will "downgrade" (their term) Doc2Go, if you installed the upgrade (with sheet2go). I forget to apply to "fix" for this problem before I upgraded to 77.
But, now that I'm up, seems to work pretty well.
I noticed a few new options, here and there.
