Audio Quality
The phone uses an algorithm that repairs lost audio
packets. When needed, a new packet is inserted
with content based on previous packets. This, in
conjunction with the high sensity and high output
power radio will enhance the audio quality
compared to a standard Bluetooth device.
File sharing
By using the Server role of the File Transfer Profile,
the phone enables the user to use a computer to
manage content files that reside in the phones file
system. Most computer Bluetooth applications
provide an explorer like user interface for the file
transfer service. When connecting to the phone,
the computer application will show the same
folders that the user can find under the File
Manager icon on the phones standby screen, i.e.
Pictures, Sounds, Videos, Themes and Others. The
content in the Games and more folder is not
exposed in the file transfer server. Opening one of
the these folder will show a list of files related to
that folder, e.g. images in the Pictures folder. Using
the computer application the user can now: retrieve
files from phone to computer, delete files from the
phone and transfer files from the computer to the
phone using the normal drag and drop
mechanisms provided by the computer.
File browsing
By using the Client role of the File Transfer Profile,
the phone enables the user to access files systems
of other devices, that support the Server role of the
same profile. After pairing with the other device, the
user can connect to the other device by selecting it
in the list of My devices under the Bluetooth menu
and selecting the Browse option that should be
available on the left action key. If the browse option
does not appear, for example if pairing was
initiated from the other device, the user can select
the Service option to update the phones
knowledge of that file browsing is possible with this
device. When connected to the file server, the user
can browse the shared folders and retrieve files
listed in the folders. The user can transfer files to
the file server device using the normal Send/via
Bluetooth option.
Media viewing
The phone can send images and sounds to a
media viewer device, for example the MMW-100
TV adaptor accessory. The user can also
conveniently run a slide show on the TV showing a
set of nice phone camera pictures for family and
friends. After selecting an image in the Pictures
folder under the File manager icon, the user can
select the Remote screen option under More. The
phone will then connect to a Bluetooth device that
can receive images and when the user then selects
View, the image is transferred to the remote screen
and displayed. When the user then selects another
image, that image is transferred to the remote
screen and displayed.

Remote control
By using the Bluetooth HID Profile v1.0, the phone
is able to act as a HID device. This means that
when connected to a computer, the phone looks
like a combined keyboard and mouse. By assigning
specific combinations of computer keyboard key
presses to each key on the phone keypad, the user
can use the phone as a remote control device for
computer applications.
The phone keypad is configured for control of a
certain computer application through a special type
of HID confíguration file consisting of an XML file
for the keypad and an image for the display. HID
configuration files can be dowloaded into the
phone using the normal file transfer mechanisms.
Users can even modify the files themselves on their
computers. A few configuration files are pre-loaded
in the phone that enables the user to navigate on a
computer desktop, control presentations and
media players.
