Yahoo! is carving its own little piece of limelight from this week's 3GSM event in Barcelona, as the web's most highly-visited portal launched a new gamma version of Yahoo! Go for Mobile 2.0 as of Monday -- just a short month after the beta rollout. What's new from the beta to the gamma? Outside of Greek designations, customers can now search directly from maps and share Yahoo!'s oneSearch results, news articles and more with friends. Ah, social communities and Yahoo! Mobile -- what a match made in, well, somewhere. But, you'll need to have one of 100 phones that the new Yahoo! Go for Mobile 2.0 works on -- and with Google also stepping it up, this is a mobile battle that's turning the screws every time we see it.
