I’m not sure I need to do this, but I have undertaken the effort to download the Win 7 and 8 SDKs, Android SDK and iPad SDK.
The Win 7 SDK was easy to find.
The Win 8 SDK was also easy to find but needs Win8 and I am still on Win7.
I knew it would be a PITA, but the Apple iOS SDK is a much bigger deal to get. First off, I need a Mac. Yeuch.
