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 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.

•Local Information, Automatic configuration items, beamed items will be found in the Inbox.
