Remember RockMelt? Neither do we, mostly, but the "social browser" -- which debuted for the Mac and PC late last year -- is back and more portable than ever. The minty fresh iPhone version plays nice with Facebook and Twitter, as well as a few other social-type things you're probably doing with your phone already. If you're a devoted user of the grown-up version, however, the networky app is probably worth a download for its ability to sync with its desktop counterpart. Peppily-soundtracked video after the break, a must-watch for those who believe in second chances.
