the structure of the content, which part is a
paragraph, which part is a heading, and so on. It
does not specify how it shall be presented.
Browsers use a default presentation for documents
without style sheets. By adding a style sheet to the
document the developer can control the
presentation of the document, the colours, fonts,
and layout.
On the Web, the de facto standard style sheet
language is Cascading Style Sheets (CSS),
specified by the W3C and implemented in IE,
Netscape, and Opera. For mobile phones, the OMA
has identified a subset of CSS and extended it with
OMA specific style rules. The CSS subset and the
OMA extensions are called Wireless CSS (WCSS).
The WAP browser supports WCSS 1.1.
My friends (Wireless Village)
To ensure inter operability of mobile instant
messaging and presence services, Sony Ericsson,
Motorola and Nokia have created the Wireless
Village Solution, an open standard. The protocol is
bearer-independent and can be implemented in
different networks. The Wireless Village Instant
Messaging and Presence Service (IMPS) includes
three primary features:
Presence
Presence information of other Wireless Village
users is received and displayed to indicate their
willingness to communicate. The user’s own
presence information is also sent for others to view.
If the user is interested in another person’s
presence status, he or she can search for this
person. If the person is found, the user may
subscribe to his/her presence information. The
presence information is displayed in a contact list.
Instant messaging
Instant messaging means “point-to-point
messaging” between Wireless Village users.
Messages can be sent to an entire contact list or to
a single user. Short message histories of the
communication are logged in a file, which can be
read off line. This is a sub-set file of the whole
communication and is limited by memory.
Groups
The user may join a chatroom and chat with the
other participants/members.
E-mail
With inbox, outbox, save draft and
reply options, there are all the
functions needed for effective e-
mail communication in a powerful
mobile phone. Constantly connected to a POP3,
SMTP or IMAP4 e-mail server anywhere on the
Internet, the phone stores messages dynamically,
depending on available memory, and updates the
inbox automatically and over the air. Check e-mail
anywhere. Reply to e-mail on the move. Friends,
family and business contacts know that when they
send e-mail, it can be received, read and acted on
immediately. Pictures can be included in outgoing
e-mails and attachments that are received.
Hyperlinks in e-mails are supported.
Personalization
With themes, the user can change many settings in
the phone, for example colours and images,
making it more personal. The phone comes with a
number of preloaded themes and pictures, and
more can be downloaded and exchanged – sports,
movie, seasonal and other themes will be available
on Sony Ericsson or operator sites. Other
personalizable features are the start-up screen and
the screen saver. Specific pictures and ringtones
can also be set for each separate name in the
phonebook.
Power save
Your screen is turned off completely a few seconds
after you last press a key. Press either of the
selection keys and the screen turns on again. Other
display light options are On, Off and Automatic.
