With Apple and ATT now allowing SlingBox to run over the 3G network and not just WiFi I was excited to see how well it worked. Pros -- it does work well over 3G. But that's not a surprise given that other video technology works well over 3G. Heck ATT sells this capability on their other phones. Cons -- MASSIVE battery drain. Intense heat buildup on my 3G phone. Without an external battery pack, I'm not sure its usable.
