How to install ios 9 gm??

Maybe I am not a Developer as my Ipad just showed an update was available and I was given 9.1 Beta OTA. I have installed it but have not used it much yet.

Max again thank you so much for your help. I really do appreciate it

Hi Thcri, yes - that it could well be that the account assoicated with that iPad is enrolled in the Public Beta program, not the Developer program.

Downlaod it from the developer site and install it with iTunes.

This is not a product being sold for $99. This is a developer program. The whole point of it is for capable people to support the ongoing development of Apps for the platform's ecosystem and report feedback for bugfixing/feature vetting the OS of the time. Example: Mom is making dinner and you offered to help. In exchange she lets you have some cookie dough. It's not finished yet! The cookies may not mix with the dough, but she'll try to bake it on there for a few.
