Former iPhone user with unlimited data, and now with the 200MB/month plan because historically I have been under 200MB/month since I use wifi at home and work. Well, I blew through that last night! I was fooling around last night trying to send a short 5 second video to my directv box and failed miserably and decided to go to bed. Apparently my Captivate decided it didn't want to go to bed and tried to send data to my directv box, with the WiFi off because my display was off. I think the WiFi is dropped when the display is turned off, but not sure. However, my Router was dead in the morning...perhaps it didn't like DLNA. Anyway, the phone tried to send 450MB of data despite not being on my local network. DNLA problem? Apparently there is no way to turn off cellular data on this phone, like there is on an iPhone. Anyone get DLNA to work with pushing videos/pictures to a Directv box?
