RSS feeds
RSS provides a way for Web sites to distribute their
content outside of a Web browser. A news Web site
might have an RSS feed which contains breaking
stories, while a magazine Web site may provide an
RSS feed with excerpts of their latest articles.
An RSS feed is a file containing a list of news items,
each of which has a title, a description and a URL
link to read more on the content provider's Web
site.
With the RSS Feeds application the user gets infor-
mation from the Internet into an easy-to-view for-
mat without browsing the Web sites. The user can
browse information from dozens - or hundreds - of
Web sites without ever visiting them.
RSS Feeds includes the following features:
•Subscription.
Update feeds manually or via a predefined
schedule.
Organize feeds into folders.
Read news items.
Send a news item to another device via email,
SMS, MMS, Bluetooth
™ connectivity or infra-
red.
Link to more information via the Web browser.

authentication

Certificate
authority
A trusted certificate used to ver-
ify that a Web site is genuine. If
the phone has a stored trusted
certificate of a certain type, it
means the user can trust all Web
sites which present a certificate
that can be verified by the
trusted certificate. Certificates
are preinstalled in the phone and
can be downloaded from the
trusted supplier's Web page.
User
certificate
A personal certificate that veri-
fies the user's identity. A bank
that the user has a contract with
may issue this kind of certificate.
