You should have stuck with #4 and the death grip issue. That's not the phones fault. It's your carrier. The death grip is a normal issue (among many if not all cell phones). The last issue with the home button seems a little much. Don't you only have to hold it for 3 seconds? Are you pressing down really hard? Im on my first iP4 and my home button is solid but will randomly get unwanted double taps. It's no biggie. I havent had rattling but would be a legit concern for me as would a home button that felt like it was going to fall off. But everything else is OCD, or you're just worried that it would grow into the previous problems you had.
