I recently got the Samsung Vibrant Unlocked from a licensed dealer, and I do not have Internet. Mobi Tv is supposed to work on WiFi and on 3G but every time I start it, it doesn't work. It keeps on giving the error, this folder is currently not available (Live TV). Now when I go to the On Demand section, all the names of the titles and their episodes show up, but when I try to click play, it says it requires a subscription. I was under the impression that I get a 30 Day trial. Also, when I click purchase, Mobi TV requires me to end WiFi, and use the network service. However it gets stuck there. It keeps saying: purchasing..., but never goes farther. Am I the only one with this problem? I would appreciate all help for this problem. Thanks.
