Hi, I'm new to this website so I apologize if a question similar to this has been answered. Anyways, I have a 3rd Generation iPod Touch (8 GB) that I bought in December 2009. A few days ago, I updated it to 4.0 from 3.1.3 I read that it has features such as multitasking, home screen wallpaper, and the Wi-Fi being on while the iPod is locked. While updating, my laptop's screen suddenly turned black but programs were still running. My iPod was still plugged in and I know you're not supposed to disconnect it until it's finished updating but I had no choice but to disconnect it. I restarted my laptop and plugged my iPod back in. I synced it, & everything was working fine. But the problem is, I don't have multitasking or the home screen wallpaper. And my iPod's battery life is fine but I hear others' iPods battery lives are getting drained out quickly. Like I said, mine is still normal. Oh and when my iPod is locked, after 30 seconds the Wi-Fi is gone. Anyone know why?
