ExtRom
From XDA-Developers
ExtROM: Extended ROM - is the section of the ROM which the distributor of the phone (eg O2, T-Mobile, iMate, etc) store their customization (eg. Today theme, ring tones, extra software) data. In WM5, the customization data will be automatically installed immediately after the initial configuration (and after every hard-reset), just after the security section. In most cases, ExtROM can be unlocked to allow users to store/build their own customizations that will be automatically installed upon every hard reset(this capability does not extend to owners of G4 devices).
