I had issues with either setting the alarms or notifications, or something. Maybe it's fixed now.
Thanks.
BerryBuzz works for setting the LED colors and such. Reminders still don't work, but not at fault of berrybuzz. In the early builds of 5.0, 3rd party apps couldn't access the profiles section to add in items. That bug has been cleared up and now BerryBuzz reminders show in Profiles/Sounds. However, once you reboot your phone (or it resets by itself, which .314 will do regularly) it resets the sounds to default. I can't speak to new builds, but thats the status of my bold 9000 using 5.0.0.314
So if you're just looking for LED notifications, it works. Audible reminders not so much yet.
I have BerryBuzz on my Verizon Tour with Leaked 5.0. It works good. All three e-mails, sms, facebook, google talk, yahoo messenger all have different color lights and more. There are plenty of others, those are just the main ones I use, but it is working great.
As was mentioned already, on 5.0.0.314, the Profiles did not keep their settings between reboots. However, 5.0.0.348 fixes this and settings are now retained even after a battery pull.
That said, if you are on AT&T, do not install .348, wait for another official/unofficial OS 5 release.
