HBO Go Coming Soon to Android, iPad and iPhone

"HBO's streaming service is coming to a tablet and smartphone near you."

HBO will soon be streaming content to your Android or iOS device, if you are a Comcast or DirecTV customer, and subscribe to HBO. But wait, where's Time Warner in all this, since they own HBO? Not offered to subscribers yet. Starting date guesswork is currently early May 2011, providing competition to Netflix. Few details are available, for example, will this service be offered over 3G (or 4G), or, why are they so adamant about not partnering with Netflix?
