I’ve been using ZumoCast for a few weeks and I love it. I installed it on my iMac and linked it to my iTunes media folder. I can stream video – television and movies – and my music to my iPad or iPhone 4 over the Wi-Fi or 3G cellular network. The video quality is much better over Wi-Fi and the 3G quality is ok on the iPhone 4. Not so much on the iPad. Viewable but not stunning. Download and try ZumoCast – FREE.
