My iPod doesn't turn on
yesterday I was installing new applications from iTunes Store on my iPod Touch when it turned off suddenly. Since then, when I switch it on, the Apple logo appears on the screen for a few seconds and then it shuts down again. The same thing happens when I connect it to my computer, the logo appears and my iPod turns down a few seconds later. The iPod doesn't reload its battery once connected to the computer and iTunes doesn't even launch. Can anyone help me ?
PS: sorry if my English isn't perfect, I live in Belgium.
