Hi,
Thanks for the answer, we are of course monitoring the memory consumption, but are getting from time to time a few LowMemWarning (especially on lower end devices like an iPhone3G), which we would have liked to handle correctly, because we found out that the low memory condition doesn't always occur directly from our game (even on a 3G without iOS4.0, mail, and safari for example are somewhat kept alive and comsuming memory), but the most consuming (or foreground) app is killed, sad world, that's usually ours
Best,
