Nokia 5700 XpressMusic

Nokia 5700 XpressMusic is a music series mobile phone by Nokia.
Overview:-
The Nokia 5700 XpressMusic is a Symbian S60 3rd Edition FP1 smartphone. It is being sold under the XpressMusic sub-brand, which emphasises music and multimedia playback. The Nokia 5700 XpressMusic is a monoblock twistable phone which weighs 115 g. It has a casing made of glossy white plastic, and a black or red matt plastic middle section. There is a rubber flap on the right hand side which covers a microSD hotswap card slot, USB port and charging jack.
The keypad is rather unusual, it can be twisted to four different positions, each allowing easier access to a specific function of the phone:
Keypad facing forward: This is the main mode of the Nokia 5700 XpressMusic, which works just like keypads on any other phone.
Playback controls facing forward: Twisting the keypad round to this position automatically activates the music player.
Camera facing away: This position automatically starts the camera application, and lets you photograph or video objects in front of you. If you are already using the phone's video player application, twisting to this position automatically changes the video to horizontal full screen mode, and it is possible to stand the 5700 on its side in this position so you can watch the video more easily.
Camera facing forward: this position also automatically starts the camera application, and is intended for self-portraits and for videophone calls. This position also lets you stand the phone horizontally on its side so you can talk to the video camera without having to hold the phone.
