The secondary VGA camera is used for self portrait while video calling. There is also a possibility to view your own image mirror-like.

The Keypad
The newly-designed round metallic keys are convenient as they protrude out but as compared to the feather touch keys in some other phones, they look quite old fashioned.
 
The left side of the phone features only the Memory Stick Micro M2 memory card slot and a dedicated Radio start/stop key. The bottom features the regular Fast Port, the in-call microphone and a hook for attaching a strap. The right side of the handset hosts the volume keys which can also be used for zooming the pictures, the camera shutter key and the Infrared port. Back side of the phone is made up of matte plastic and sports the main 3.2 megapixel camera with its active cover, the loudspeaker and the Xenon flash.

For a contact you can add Phone number, Mobile, Home, Work, Fax and Other. Another field for a contact is for email and web addresses. The third is for assigning a picture and a custom ringtone. The fourth for Address and fifth for additional information and birth date. When you add the birth date, the phone asks you whether you would like to add it to the calendar and set a reminder.
