I've been using this ROM all day and I can only say that it's freakin' FANTASTIC.
Battery life has been great. Everything moves quickly. Even PhoneWeaver seems to be playing nicely with it- something was causing PhW to crash occasionally when I was using 4.8. All my customizations have gone smoothly.
The only small issues I've had:
- Opera crashes occasionally. When browsing to a page, it just disappeared. Restarted and worked fine for a while. Happened only twice.
- I had PI8 lock up at one point when I was assigning a ringtone to a contact. Soft reset and haven't seen it since.
- I had to install the background4allpages cab myself.
- I miss having the extra calendar events showing on the Home tab.
I realize that very little if any of this is the fault of the ROM. I just wanted to put out there what kind of things I was seeing. It might be nice to know if anyone is having the same issues with the same or different programs; It would also be good to know if anyone is using a PIM/Calendar app that was comparable that had none of these issues. I don't think that any of the problems are enough to get me off of them, but it might be helpful to others who want to try these programs.
