Apple ipod

I can not sync my iPhone!?

Ok, so that a week ago I connect my iphone to sync with my itunes, and recognizes the synchronization and wouldnt wouldnt start, Well, I tried to update iTunes and when I did, he finally started to sync with iTunes and deleted all songs from my iphone, and began to put there yet, but is synchronized over a minute at a time, and then disconnects. Now I'm out of my 900 songs, only 100 made it back to me iphone. I made at Best Buy and the Apple representative. was there and connected to the computer so you can not upgrade the software on the iPhone and he said it was not the phone now, and he said to get a new USB cable, so I did, I got a new brand and not always does not work, I am also reset the sync history. Im sorry it takes so long, but it's really frustrating, and I do not know what to do. But thanks to everyone who can help everyone.:)
