I know it's not supported but it works fine over wi-fi. I followed the instructions to every hack on the forum to get my iPhone to work over 3g with slingplayer (updated firmware for my sling box, edited the VoiPover3G, Trick3g, and what not) but nothing, still getting the cannot connect message and I'm just starting to think its because I have an AV and not a newer slingbox. Can anyone confirm that it works for an older slingbox like the AV or is everyone using the updated slingboxes? Thanks so much in advance
