When Amazon's Instant Video app made its way to the iPad earlier this month, it gave users yet another way to stream content to their mobile devices, but was lacking some key features. Fortunately, an update to the app has rolled out to fix one of the major omissions: search functionality. The added tool provides instant results when typing a name or title, and the search can be filtered to display all videos or only those available for Amazon Prime subscribers. Prior to the update, users were only able to browse through "a selection of top Prime Instant Video titles" or items added to their Watchlist. With over 120,000 videos available for streaming, the lack of a search function was a major downside to Amazon's app. The update also includes various bug fixes and an improved notification bar, but unfortunately does not add AirPlay support or resolve the issue of requiring Wi-Fi connectivity to stream videos.
