I do use Google contacts through gMail to manage all of my contacts. Gives me piece of mind that if my phone ever bricks, I have everything I really care about backed up. I could care less about my apps, those are easy to get back. My Google contacts DO sync, but they won't like with their respective FB profiles, at least not all of them. So last night I did a hard reset with the v3 leak and started over. Thought maybe it was just a fluke. But no, contacts are still not right. They don't crash as much which is good, but the FB pictures don't sync. The pictures are really all I care about. I don't care about status updates and everything.
I talked to 2 different Verizon store guys the other day who had Eris' and said they had all the same exact problems I am having, give or take. That's why I'm searching high and low for an Incredible. I can deal with my Eris for the next month or so if I have to, but I'd prefer not to.
