Is there any way for me to view a webpage on my iphone in Safari offline?
Thanks Kevin Grabher for the answer.
For those who want to use this, to get to 'Send As' you should press 'options' after pressing the bottom middle button.
There are natural and understandable limitations, namely that you will need to make sure you arrange things such that you capture all the assets in doing this. There's several ways to do so. For me I just inlined the assets I needed, hosted locally on my computer, accessed my local server, did this webarchive thing and hey presto, it works!
