I did have device with Symbian S60v3. I browsed internet and it worked perfectly fine, on Opera Mini/Mobile, pages rendered just as on desktop and you just zoomed on area you wanted to read. It did have proper filesystem and explorer available. One time I registered domain, write some placeholder content HTML (on QWERTY keyboard, none of that crap touchscreen keyboards!) and uploaded it through FTP, all on the phone. It ran some games too, including SNES emulation and others. That felt like a pocket computer. I don't think you could do most of these things on first iPhone, it was feature phone by comparison.
