Not strictly accurate I am afraid. What is commonly referred to as ROM is actually Flash EPROM - Eraseable Programmable ROM. Some 30 MB of this contains the Operating System - which is write protected, but it can be overwritten. If this was not possible it would be impossible to upgrade or change the OS. The remainder is known as Built-in-Storage (BIS) and can be used for storing applications or data files. These can be erased but, because they are in ROM rather than RAM, they will survive a hard reset or total power failure.
But you cannot erase or overwrite any of the files which comprise the OS - only the complete OS itself. This is a pity because I would like to gain extra BIS space by erasing programs which I never use like Pocket Excel (I use PlanMaker and/or Spread CE Instead) Pocket Word (I use TextMaker instead), Data Backup (I use Sprite and Spb backup instead) and several others. Unfortunately this simply cannot be done
