m.sitename looks the mobify

I have install the mobify to the m.XXX.gr and I set the "Mobile Sitename" of mobilejoomla to be m.XXX.gr
when I navigate from iphone it return to the root of my site www.XXX.gr

Why does this happen?

"Mobile Sitename" is not an URL, it's just a short title for website. If you like to use other independent domain for mobile site version, type it in "Domain name" fields.

ok thank u.

it works.
