Yes, if you jailbreak your iPhone, install openssh, SSH to localhost and start your specially compiled emacs for arm binary. A bluetooth keyboard is recommended. If it's just about viewing you could export to html, or export to a file that another Outliner app can easily import.

The same method of operation (native emacs) on Android is much more convenient, by using a Linux chroot (Linux Deploy). Android users also have it much more easy in the org compatible App department, they can use Orgzly!
