iPad iOS 10 beta on iPad 3 - sources or information appreciated!

[RhodesRoads]

Hi guys!

So I recently become a proud owner of an iP3, which I'm using solely as sound module for a MIDI keyboard. It does the job, but there are loads of fantastic synths that aren't compatible with iOS9 anymore. Even after JB & being able to download some older software from AppStore, there are still some that I would like to use, but requiring iOS10.
I know Apple had the iOS10 beta available for iP3, but in the end they've dropped the idea to provide iOS10 support on iP3s. Does anyone have the mentioned iOS10 beta installation profile by any chance? I've found some links in YT videos/forums, but they're not valid anymore... Halp :c

You prolly need that beta IPSW rather than configuration profile to install that beta version of iOS 10, plus even if you happen to find the config profile it is expired already, so you prolly can’t even install it.

I’m surprised to see iPad 4 doesn’t sell the same price as iPad 3 in your region.

iPad 3 will not install/run anything after iOS 9.3.5, apparently.

There was a beta version of snow leopard that could run on PowerPC Mac, just that the final release version didn’t work with PowerPC. MJD had a video about this, so I think what OP thinks here actually makes sense.
