While I appreciate the poll, the choices do not allot for what device. And since there are far more votes than posts to the thread, it is hard to discern where problems may lie.
FWIW, I have a Mini. I bought a second one yesterday at BB that was preowned. While I understand it may work fine on that after the upgrade but not on my original, I was not going to do it first on my original unless I carefully monitored this forum first. Least now I have my own test for hands on and just not for problems but if I like IOS 7 to begin with. I have run no Betas, not worth it as beta is beta.
