This is not a joke, after this configuration has the phone a very quick menu.  
(Place the current date in the phone on the 01.05.2005.)
The first two tasks must be created. This is done with the following menu:
>Options
     >New entry
           >Task

Create the following two tasks in the following order:

 1.Task

    *Subject: Speed
    * Due Date: 04.08.2005
    *Priority: High 

 2.Task

    *Subject: Qoukie
    *Due Date: 04.08.2005
    *Priority: Low 

Confirm with OK both tasks.The calendar does not close before!

Choose now the task of view on the following menu:

    *Options
          *Task view 

Set Speed first, followed by Qoukie menu is done:

    *Options
          *Done 

Under this approach, you can close the calendar and the current date back correctly.

From now should speed the navigation menu significantly increase. Also, the gallery should now be a performance boost get.

After a reboot or reset the phone, the effect is lost.After the switch, everything has to be repeated

*This is for all s60 Devices.
