I would like to share with you a way to access the Address book without using the PIM Api in sony ericcson k800i. I am not aware of such a feature in Nokia phones.

Methods

• create a text field in a form or a custom textfield in a canvas.
• When clicking the edit button switch the action to the phones default textfield.
• Now the phones default textfield appears and on clicking the More button u will be directed to the Phones Contact list.
