Social networks keep you connected while you’re on the go, making them popular apps in the Android Market. Twitter updated its Android app after usage doubled these past few weeks, and Plixi (formerly TweetPhoto) debuted its app this week as well. Navigating with your Android is also an easy task, with MapQuest’s launch and Citysearch adding a Deals app to its catalog.

Sports Illustrated has gone digital too, launching an Android app as part of its new-age subscription plan. Access the mobile edition anytime, combining the magazine and its mobile web features, including exclusive photos, stories, videos and interviews. Being the SI fan you are, you’ll surely appreciate the live scores and news feeds far more than bikini-clad models.
