Most of us don’t have a start page on our mobile phones, but Yahoo is making a good case here at CTIA for making it the new Yahoo Mobile. This redesigned portal, available both as a mobile Web site and iPhone app, delivers the news you want, links to the latest videos, e-mail (from Yahoo, Gmail, and others), Yahoo instant messaging, and social networking tools like Facebook and and Twitter. In our brief hands on time with Yahoo Mobile we came away impressed with its simple and clean design, as well as how easy it is to customize with RSS feeds and shortcuts to your favorite sites. Plus, it’s a cinch to follow news on specific search terms, like Apple or The New York Giants. The iPhone app is a little more robust than the site in that it supports more images, and it’s caching action makes it faster than the Web version, but we think Yahoo has done a solid job on both fronts. And presumably the iPhone app will get better once push notifications become available with Apple’s 3.0 software. Also on the horizon is a standalone Yahoo Messenger app for the iPhone, complete with emoticon support, and a smart phone Yahoo app (similar to Yahoo Go) that has a nice tile interface you can personalize with tons of widgets. It will also have the Opera Mobile browser built in.
