Sorry for such a poor question but the font in question is:
I tried using http://www.myfonts.com/WhatTheFont/ to identify it but no joy.
You are looking for Yukarimobile (it's free, too):
I found it by monochromizing it and cleaning up the edges a little bit, then fed it to WhatFontIs.com.
Could very well be custom. You could try clipping the extensions off h and m and see if WTF gets it.
If not, this would be very simple to just draw from scratch.
