So.... ICS has been released via official Vodacom and MTN channels.
Go go go go go!
I just upgraded this afternoon :) So far so good - the phone is much faster!
One issue though: whenever I reboot the phone, I get two errors in my notifications, 1 about camera permissions, the other about Gmail permissions:

When I click on them, I get: "Google Account Manager Has Stopped".

Googling this shows that some others have gotten the same thing, but finding a solution is proving more difficult. Nothing seems broken... but I haven't chcked everything yet. I can access my Gmail account and the camera just fine, etc.
Any tips? Is this a matter of reinstalling the Google Apps package?
