Perhaps I'll stick with my "early adopter" 2.0 from yesterday for a week or so since it seems no one can access the servers or reactive there phone if they manage to get it updated.
I think waiting is my plan too.
I looked at both 5A347 2.0 versions and it does look like today's is slightly newer, and has less firmware files in the firmware folder.
Isn't that just because the 3G info isn't needed for EDGE iPhones or is that because yesterday's viruses aren't in today's update (just kidding)?
Since i'm experiencing no problems with my phone at all and really don't feel like bricking it or watching iTunes go in circles for hours today, I think I'll wait a bit.
