White Paper T310/T312
7 January 2003
Full graphic 256 colour display
The large colour display of the T310/T312
enhances viewing, facilitating high-quality
multimedia messaging and personalized imaging.
The standby display looks like the desktop in a
computer, with the menus presented as icons.
Joystick navigation on the keypad
The T310/T312 has an easy-to-use 5-directional
joystick function. Using finger or thumb, you can
easily navigate the new T310/T312 menu system.
When you arrive at the required function in a menu,
instead of pressing Yes, just gently press the
joystick and the feature is activated. The T310/
T312 MMI is adapted for easy joystick navigation.
Browser supporting WAP 2.0 - XHTML™
The T310/T312 supports the WAP 1.2.1 browser
and protocol stack as well as the WAP 2.0 browser.
The browser supports the markup languages of
WAP 2.0 – XHTML Mobile and XHTML Basic.
These two subsets of the Web standard XHTML are
supported by all major Web browsers. An XHTML
page can be viewed in both the WAP browser and
in any standard Web browser. All of the basic
XHTML features are supported, including text,
images, links, check boxes, radio buttons, text
areas, headings, horizontal rules and lists.
In addition to XHTML, the browser supports WML.
The user can navigate between WML and XHTML
pages.
T310/T312 also supports cookies, often used by
Web sites to store site-specific information in the
browser between visits to the site. Cookies are
often used by e-commerce sites (shopping carts
and wish lists), and to save the user from entering
the same information more than once.
GPRS
GPRS uses Internet-style packet based
technology. It uses the radio link only for the
duration of time that it transfers data. GPRS offers
the user the speed needed for satisfactory mobile
Internet usability. The T310/T312 supports GPRS
3+1.
Design
The basic form gives a strong and sophisticated
product image by using a simple cylindrical shape
with relaxed, smooth surfaces and slightly curved
sides featuring concave grips. The bezel
surrounding the display wraps across the front
surface creating an innovative wide-screen design
element. The split-line speaker outlet between the
front and the bezel enables a completely new look
reducing unnecessary ornamental detailing. The
navigation keys are clustered into one design detail
around the joystick to ensure best possible
ergonomics. Below the keypad is a small
expansion of the surface, featuring a separate
detail, which enhances the grip while pushing the
lower keys. The front cover is not exchangable and
the battery cover slides into place. There is also a
loophole for a carrying strap accessory.
Customization
The T310 has a separate co-brand inlay part for
more flexible customization. The co-brand inlay is
snapped on to the front, in the area below the
keypad, and is mounted on the phone as the last
step in our production chain. This makes it possible
for a shorter lead time when printing operator
details on customized phones. Furthermore, the
co-brand print is covered with a top coat for
greater wear resistance.

Content such as games, pictures and sounds can
