Physical Dump of BlackBerry 8520

A recent examination using CelleBrite Physical Analyser of a BlackBerry 8520, shows an ICCID and phone number in the summary section of the report. However, these do not relate to the most recently used SIM card in the handset. Where do these numbers come from and how are they stored? After sending the dump to CelleBrite, they have confirmed that data for the ICCID and phone number from the most recently used SIM card isn't anywhere within the dump..
