The recent slew of hard crashes (requires reboot) on my iPhone has lead me to ponder: Can the NAND storage of the iPhone become corrupt (entirely or partially) from software errors? In other words, can my iPhone's physical integrity be damaged due to all these crashes? This may be an ignorant question, but I can't find a source ("Genius" Bar included) that can answer this one way or another. Your thoughts?

Most likely not.

The iPhone supposedly has two 512 Megabit SDRAM chips (equal to 128 MB RAM) stacked underneath the main CPU die. This is what the OS and applications would use when actually running, and it's just like the RAM you have in your computer.

I suppose it's possible that an application crash could cause data corruption in the flash storage if it was trying to write to the filesystem while it crashed (which may compound any software problems until you restore the device), but I highly doubt any software activity could result in the physical damage of the NAND flash.
