Moving Ipod triggers home button action

I've had an ipod touch for years and got used to how it works. I just bought a new one, and one thing really annoys me: when I move it from a stationary position, it responds as if I had touched the home button. I am used to picking it up and then pressing home in order to, e.g., restart a paused podcast, or just to check the time. But since I'm used to that, I often pick up the new ipod and press home, which now (since it acts like "home" was pressed *twice*) moves me to the login pad, so I have to login first before seeing the time or restarting my podcast. Worse, it only does this about 90% of the time (it may depend on how much or quickly I move it). Is this just the way new ipods work, or is this a setting option I can turn off?
