P800/P802
White Paper, January 2003
19
Note: The extensive MMI of the P800 means that it is impractical to hold many languages inside
the phone, as is done for some other models.
The second 16Mbyte bank of flash memory is divided into two parts. The first 4 Mbyte is
reserved. It is essentially an extension of the ROM area.
The rest of the second bank provides a ‘C:’ drive of 12 Mbyte capacity. This behaves just like a
normal disk drive. Some folders can even be viewed and managed from a connected PC. In the
Chinese version the reserved area is 7Mbyte and the C: drive is 9Mbyte
When a P800 is updated at a Sony Ericsson Service Point, or over the internet using the Sony
Ericsson Update Service, all three banks of flash memory will be rewritten. User data that has
previously been backed up to a PC can be restored to the C: drive afterwards.
User Storage
The user storage space (C: drive) is shared across applications without any imposed restrictions,
apart from the whole space becoming full. For example, one user might use the entire user
storage space for photographs, in which case over 200 can be stored. Another user might load a
third party street map application and a number of street maps. In this case, the application will
take up some of the storage space and so will each map. When space becomes limited, the user
can choose to remove some maps.
Unlike a PC, the user does not need to be aware of the underlying filing system. Applications will
always make sensible choices and store information automatically, simplifying management of
data. Third party applications may implement more complex file management solutions where
required.
Additional storage space is available by using Memory Stick Duo. A 16Mbyte Memory Stick Duo
is included with the P800. Any number of Memory Stick Duos may be used with the P800. See
‘Memory Stick Duo’ later in this paper for more information. Memory Sticks up to 128Mbyte
capacity are supported.
Depending on the application, data can be beamed, mailed, uploaded to the web or transferred
over the link to a PC in order to archive and create free user space on the P800 – see
‘Synchronisation and Data Transfer’ later in this paper.
User Storage configuration in a new P800
Applications and information are placed in the internal storage of the P800 in the factory. This
provides sample demonstration, educational, multimedia and fun content so that the P800 can be
used directly out of the box. Much of this can be deleted by the user in order to make the space
available for personal use.
This section describes the case for a generic (non-customised) P800.
User Data
This space is initially empty. Normal uses are:
• User-data associated with built-in applications (e.g. Messaging, Contacts)
• Applications installed by the user
•
Multimedia content added by the user
Settings
Settings such as dial-up networking and e-mail account information. Initially Empty.
