i have the 3rd party app tvout2 and was wondering this is there a way to use an iphone dock to get this to work i have a 7 speaker surround sound and was wondering if there is a way to get the audio and video to transfer to the tv from it the audio comes through the iphone dock but no video to tv and if there is another cheap cable i can buy to do this as well let me know my trouble with another cable is will it charge my device while it is running

oh forgot to say i am on iphone 4 with 4.0.1 and using the pdf exploit to make my phone think i am on 4.0.2
