I got a new USB cable for my IPhone 4 and it won't sync with my iTunes, how do I get it to sync?

I just bought a new USB cable from Micro Center, and I got it to sync with my laptop and download music to my phone using iTunes. It won't sync. How do I get it to work?

Because it is not an Apple specific USB, meaning that it may be able to CHARGE, but not SYNC.

Omg I didn't even know there had to be an apple-specific USB!

  • Where can I get an iphone lightning to USB-B cable? The iphone comes with a lightning to USB-A cable, but I need one that's B type. (I already tried an A-to-B adapter and it did not work for my intended purpose.) This seems like something that should be available but I can't find any such product for sale online. Any help would be GREATLY appreciated.
  • My iphone won't charge with my usb cable? I have a usb cable which i always use to charge with my wall charger. Yesterday i wanted to charge my iphone 4s with it but suddenly it didn't work. No alert, no warning; nothing. Then i turned my phone off and i plug the usb cable in. And my phone turned on without i pressed the power button! I know the usb cable is working and maybe the problem is in my phone software. Anybody know how to fix this? What kind of software can fix my phone? Ps: it's jailbroken.
  • My iPhone USB charger cable won't go in properly on my computer? My iPhone USB charger cable worked perfectly when plugged into my computer (its how I got my pictures off my phone, into the computer), but now it still plugs into the computer, but it won't connect into the phone. There's nothing wrong with the cable as far as I know, it plugs in and charges perfectly when in the wall. But now it won't connect to my computer.
