WebFig is nice tool but oriented to desktop use. When used on small screen mobile devices it is not that useful. It is hard to navigate, click and set options as interface is stil designed as for desktop.

Are there plans to provide mobile friendly webfig user interface?

Why would you need that ?

on My HTC its working fine

Well, it runs fine on my xperia x10, but it is hard to use as user interface is not adapted to such a small screen. Laso it lacks good support for touch screen usage.
