After having Yahoo as the exclusive search provider for T-Mobile over the past year, the wireless company has decided to now go with Google, saying that is what the customers wanted. Ian McKerlich, T-Mobile’s director of mobile web and content, said other reasons also played a roll in the decision, as they were the first carrier to work with Google on deployment of its Android-based devices. T-Mobile began updating its web2go portal with Google last month in preparation for the change, as well as making it easier to personalize, and more touch-friendly. These changes have led to a 300 percent increase in web2go traffic per customer, though you can still use the browser to go to any search provider you choose. 94 percent of all T-Mobile devices use the web2go portal, including BlackBerry Smartphones, the Motorola Cliq, and most feature-phones. Now with this complete, Google has exclusivity deals with Sprint & T-Mobile, Yahoo is still partnered with AT&T, and Microsoft Bing has been with Verizon since last year. As Google continues to grow and expand, it will be interesting to see in the coming years if AT&T and Verizon end up signing exclusivity deals with Google as well.
