Nokia smartphones had http+html browsers back in 2001. I don't know how many mobile optimized sites were there, but the browser on my 9210 was pretty usable (though not everything worked, of course). I used to save full pages on my desktop and copy it on the 9210 to read while on the go. (Well, we didn't have Pocket back then, and while I definitely wanted to develop something similar, I just couldn't make myself do it in Symbian's C++ dialect.)
