My buddy @ASacco mentioned yesterday on CIO that T-Mobile USA would be replacing their default Yahoo! search engine with Google’s search engine. Today I went into the T-Mobile’s Web2Go BlackBerry browser application and searched “blackberryrocks” and sure enough, the search engine now being used is Google’s.

According to mocoNews, T-Mobile USA ended a year long deal with Yahoo! in favor of Google:

The deal shifts the U.S. mobile search dominance away from Yahoo and in favor of Google, which now works with two of the top four carriers. The hand-off between Yahoo and Google was completed as recently as Wednesday, and when visiting the T-Mobile portal from a BlackBerry today, it showed Google as the prominent search provider at the top of the screen—not Yahoo (NSDQ: YHOO).

A Yahoo spokesperson confirmed it was no longer working with T-Mobile for search, and a T-Mobile USA spokesperson declined to comment.

Sources say T-Mobile is also working with search provider Medio Systems, which typically indexes and returns results for content, including ringtones and wallpapers, unlike Google, which returns results for the web.

I personally welcome the change as I’m a big fan of Google, their search engine and their products. What do you think about this search engine change? Did you prefer Yahoo? Feel free to share your thoughts in the comments!
