Thats a tinyMCE thing

Editing via the iphone Safari app works with the TinyMCE editor if you select the HTML button and add text that way. You have to also add your styling tags via the HTML view as well.

Some of the formatting button will work once you've added text that way, but it's wonky.

This also works if you choose an HTML block.

It's slow, but if you're remote and want to fix something or add something simple it's an option.

I've tried moving blocks on the iphone, but it doesn't work. Still, pretty cool...
