The report however does not reflect the recent release of the Verizon iPhone. (New York Times) Meet Mobilewalla, a recent startup out to help out new app makers with an online catalog and search engine that ranks each app for mobile platforms including iPhone, iPad, Android, BlackBerry and Windows Phone with a score with a score from 1 – 100 based on 114 different variables. The company should announce further plans later today.
