I installed Beta 18, I wiped everything before installing
I still have the launcher FC, mostly when I unlock the phone, I switch to Go Launcher
Calendar does not display correctly, I replaced Calendar.apk, CalendarProvider.apk, and CalendarWidget.apk that are in /system/app with the ones that were included in the "Velocity-1.2.1-Patch-Signed" and now the Calendar displays correctly.
I have not had any other issues with this, the phone is very fast and battery life is great.
Thanks for the work on this.
