Except the iPhone (and related devices) don't have wear levelling. Even if they did, there's edge cases where the user fills 95% of the disk and the OS has to page with the remaining 5% (this would require a very intelligent wear levelling algorithm that could optimistically move in-use blocks)

The phone would be restarting all the time, or they'd be doing some sort of weird copy everything background task while the phone was running (and things would get really complicated if you tried to sync in the middle of that).
