The new one that I bought seems to crash a bit often even though I don't do anything demanding. This happened when I browsed the movie section in iTunes and the comic book store in the Marvel Comics app. Nothing else was running in the background. What I mean by "crash" is that it simply closes the program and goes back to the menu screen. I checked the diagnostics and it said it was a memory issue. It doesn't bother me too much since I can easily exchange the model but I was wondering if I got a dud, or is anyone else experiencing this? If so, I'll just wait for an iOS update.
