Sony Ericsson Developer Support
Sony Ericsson offers developers professional tech-
nical support services. The service can be pur-
chased from the developer Web portal, as part of
the Sony Ericsson Core and Core+ membership

are two levels of support, described below:
• The Basic E-mail Developer Support is an
annual support service included in the Core
membership that provides developers with all
the basics to successfully develop world-class
applications for Sony Ericsson products. With
this support contract, developers get access to
Sony Ericsson developer support engineers via
e-mail with same-day response, five technical
support incidents as well as the ability to pur-
chase more.
• The Priority E-mail Developer Support is an
annual support service included in the Core+
membership that equips professional develop-
ers with everything they need to successfully
develop world-class applications for Sony Eric-
sson products. With this support contract,
developers get priority access to Sony Ericsson
developer support engineers via e-mail with fast
response times and up to 50 technical support
incidents.
Infrared transceiver
Infrared communication creates a data link
between two communications devices through an
infrared beam of light. On the J200, this link is used
to connect with other phones (for example, the
Sony Ericsson T610), and other hardware support-
ing the standard. The Infrared Data Association
(IrDA) has set the hardware and software standards
that form the infrared communication links. The
J200 complies with the IrDA 1.2 specification,
which defines how mobile telephony and commu-
nication devices can exchange information.
