The only thing I really miss is Social Duplicator that allowed me to have multiple copies of any app installed. I have three Facebook accounts and this allowed me to have a FB app installed for each one. I was still able to sync all of those three FB apps to my iPad/iPhone, they just don't open even though I had to install app sync beta to get them to install.
I can block all ads by using untrusted hosts blocker which has been updated.
Other than social duplicator, I am not missing anything else. Happy I updated and JB.
