I’m working on a scrolling support for iframes on ipad and iphone right now.
I have now made examples for all supported setups here:
Please note that on this page when viewed on an older iphone my WordPress theme is not really working well as 100% is only 320px but the auto content example at the bottom has ~1000px. But the feature that you can scroll in the first example should work fine.
Please provide feedback if something is not working for you at the e-mail you find here:
