I know English isn't your first language, but I don't understand what you mean by.
Maybe you want a mobile-friendly version of the old userpage. In that case, I'm sorry. osu!'s webpage will be replaced by the new version along with the release of osu!lazer sometime this year. And the old site will be never mobile-friendly
if i got it right, youre asking for a mobile friendly version of the website.... you can try opening the new version of the website here: https://osu.ppy.sh/home .... i tried it on my phone and it mobile friendly.... :3
