Question User Agent string

I'm using habit browser on my tablet and the User Agent PC string is giving me the old version of google search on the web.

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; ja-jp) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16

Anyone know what I need to change on this to get the newer version of google?
