How to
Using Twitter on my mobile phone
Want to use Twitter? It's easy, but first you need to install Twitter on your mobile phone and create a Twitter profile on www.twitter.com before you can use the service.
Tap Twitter.


If it's the first time you use the application, you need to log on.
You can now use the application.
Please note: Twitter isn't part of the original application package and therefore only a general description is given here.
You have a number of options, such as:
Write status updates
View status updates from people you follow
View messages sent directly to you
Turn status updates on or off
Tap the Home key to return to standby mode.
