I have to say, while I usually encounter no major issues with new (official) first versions of iOS, I've had several issues with this version, including a conflict with my Office 365 (Exchange-based) email at work. Yes, I tried removing and re-adding the account, but that didn't work. I've also had some connectivity issues, again in my work environment. All was fine before 9.0 came out, so I can't blame my network here. I'm hoping that Apple is getting wind of some of these issues we're reporting on here; otherwise, I'm installing the 9.1 beta and reporting the hell out of every problem I have.
