I was listening to music on thee speaker. When i hit the home button, it wouldnt take me to the home screen. I kept clicking the home, but all it gave me was the little thingy that pops up for music. I could still tap everything in the iphone thing. But stupid me, i thought i could stop it by taking a snapshot. I did so, and baam stuck white screen with music playing (a rather odd song might i add). So i got my macbook air and tried to solve it by restoring it, but it said the iphone update server cannot be contacted. I tried again this morning... and it extracted the software, but said this iphone could ot be synced. an unknown error occured (-19). Please help, it will be gladly appreciated.
