M600

February 2006
email from the PC is transferred in to the corre-
sponding 'synchronized email account' inbox on
M600. Messages and replies written using this
account on M600 are transferred and sent via the
PC.
Web based email can, of course, be accessed
using the M600 browser.
Email folders
Messaging accounts have the following folders:
Inbox, Outbox, SIM, Draft and Sent. You can create
additional folders if you want,
see Local folders below.
Local folders
To improve the organization of your folders you can
create more folders locally on M600. Local folders
are only visible in the Messages application. Local
folders cannot be created on the Memory Stick™.
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.
M600 is prepared for these solutions and a rich set
of 3rd party applications are available from compa-
nies, such as Extended Systems, Intellisync, JP
Mobile, Research In Motion (RIM)/Blackberry,
Active Sync, Seven, Smartner and Visto.
Push methods
The solutions use different methods to push the
messages, usually IP push, by listening to dedi-
cated ports when a session is active, this is similar
to instant messaging solutions. Some solutions
may also use SMS with triggers to the application
to start a sync/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 using a fixed password for push mail. Initially
key exchange is also done by using device param-
eters 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 some-
times theft and loss protection through wipe-out
commands and lock-out.
Unified mailbox
SMS, EMS, MMS, Local Information, Beamed and
Autoconfig messages are all stored within one uni-
fied inbox in messaging.
•
SMS (Short Message Service): With SMS a user
can send text messages containing up to 160
characters to and from GSM mobile stations (up
to 70 characters using unicode text). M600 also
provides concatenated SMS, that is, the user
can write a longer message and M600 will auto-
matically send it using more than one SMS. You
can reply to an SMS with an MMS and send a
fax using SMS as the bearer. There is enhanced
support for delivery reports and short message
class support.

items, beamed items will be found in the Inbox.

Enhanced Messaging Service (EMS) adds pow-
erful functionality to the well-known SMS stan-
dard. An EMS can include; sounds and
