Yeah, I was wondering about this myself. I just got a Nokia Lumia 735, and just tried to copy a postcode from like 3 browsers, but couldn't. On an iPhone it's easy: you can just copy text from anywhere in the browser. Anyone figure this out yet?
Hmm. It works for me. Just tap on the word you want to copy. It should highlight where you can expand the selection to whatever you want. From there they're should be an option to copy text.
