White paper G900c

corresponding 'synchronized email account' Inbox
on G900c. Messages and replies written using this
account on G900c are transferred and sent via the
PC.
Web-based email messages can, of course, be
accessed using the G900c browser.
Email folders
Messaging accounts have the following folders:
Inbox, Outbox, SIM, Draft and Sent. Additional
folders can be created, see below.
To improve the organization of folders more folders
can be created locally on G900c. Local folders are
only visible in the Messaging application.
Push email
Push email is a method of 'pushing' or forwarding
email to mobile devices as soon as a message
reaches the email server. These solutions may also
include calendar and contacts synchronization.
Push email solutions allow email messages to be
delivered in the background in the same way as
SMS or MMS messages. G900c is prepared for
these solutions with Exchange ActiveSync™ pre-
installed. A rich set of other third party applications
are available.
Note: Push email applications are generally quite
power-consuming.
Push methods
The various solutions use different methods to
push messages, usually IP push, by listening to
dedicated ports when a session is active. This is
similar to instant messaging solutions. Some
solutions may also use SMS messages with
triggers to the application to start a synchronization
or download, sometimes referred to as pseudo-
push.
Security
All solutions use end-to-end security using SSL,
3DES or AES encryption. Most solutions are based
on the use of a fixed password for push email.
Initially key exchange is also done by using device
parameters such as the IMEI number. A few
solutions combine push with one-time passwords
that are limited for a certain amount of time before
being re-entered. Many solutions have functionality
for enforcing screen passwords. There is also
sometimes theft and loss protection through wipe-
out commands and lock-out.
Exchange ActiveSync™
The push email application Exchange ActiveSync™
is normally pre-installed in the phone and ready for
setup.
With Exchange ActiveSync™ corporate email,
calendar items and contacts on a Microsoft™
Exchange Server 2003 or 2007 can be wirelessly
synchronized with the corresponding information in
the phone. When on the move, the user can easily,
for example, look up details in the company global
address book or accept a request for a meeting.
All changes in the phone are automatically
synchronized with the user’s Exchange Server
data. Similarly, all changes to the Exchange Server
data are transferred to the phone. With the Direct
Push feature activated, synchronization is
immediate. If the user, for example, receives a new
email in Outlook™ (or a similar client) it is instantly
copied to the phone.
Web mail
Web-based email or Web mail refers to an e-mail
service intended to be primarily accessed via a
Web browser, as opposed to through an
application such as Microsoft Outlook or Outlook
Express.
