My email is working fine. I have my work e-mail synced via Exchange and it's been receiving e-mails the past week I've been using this ROM.
I'm on V11 right now and it's smooth as silk. Calls are working great (no SOD after hang ups). I haven't found anything wrong with it so far. Sleep times are great as well, checking with CPU Spy. I'm around 85% deep sleep right now and battery life is better than any other version of this ROM to date.
Great piece of work.
I strayed for a couple days, playing with the leaked ICS update for AT&T. I was wondering, can I go from my nandroid of v8 and just flash v11, or do I need to wipe everything 1st? I really don't want to, but I could see where issues may arise if I don't.
