iPhone is not uploading on iTunes
HI I am trying to upload my iPhone to my iTunes account to upload all my pictures on my phone to my computer. However, for some reason when I plug my phone to my USB that is connected to my computer is not reading my phone. my iTunes is updated and my phone is still being charged when it's plugged in. When I plug my phone in iTunes pops up and says "iTunes could not connect to the iPhone because invalid response was received from the device" could you please help me get this working I would like to download my pictures and put music on my phone.
THanks
