I am trying to use the "Sync iPhone over Wi-Fi" feature. I was able to do it successfully once.. I left to go to the store.. came back.. tried to manually sync another song. When i did, it couldnt locate my phone, even thought it was listed on the device section on iTunes. So i had to relaunch itunes to get it to recognize my phone. Is this normal? Is there a better way to get my phone to show up? Is 6 minutes long to transfer one 6 minute song?
