Sync my new IPhone to ITunes?

I recently got a Iphone, before that I used an Ipod for my music. I plugged my Iphone into my computer (i have a PC) through USB awhile ago but my computer had problems so it would shut off suddenly. Then recently I changed the name (for example, "So-and-so's IPhone"). Today, after getting my computer fixed, I plugged it into my computer to try again. Except this time, it makes the little "dundun" noise but doesn't charge my Iphone or really recognize it. I went to my devices to see if it saw it and it's not there. Someone help? Haha

You have a bad wire, or the phone is in sleep mode.

  • Why won't my new Iphone 5 sync to my old Itunes? I don't have my old Iphone 4s, it was stolen. I got a new Iphone 5 and now I'm trying to sync it to get my music off my old phone. I didn't have Icloud turned on on my old phone and on Itunes, the panel to the left that the apple website keeps saying to go to isn't there. Please help, I have hundreds of dollars worth of music on that phone! I have also downloaded the most recent itunes already

  • New iTunes 11 won't sync iPhone and iPad properly? Ever since I updated to the new iTunes 11 a couple days ago. The apps don't sync properly within the two devices. It used to be that whenever I deleted an app from itunes it would automatically erase it from both of my devices. Now even if I delete a few apps they will still be on them and I have to go in them and manually delete them, its not that big of a deal but its a huge pet peeve.
