I'm rather torn on my opinion about this phone. The features it has to offer are absolutely superb, a brilliant 8.1 megapixel "Cyber-shot" camera produces superb quality photographs and videos, even when it is zoomed in on an object.
The walkman on the phone is great, i already have hundreds of songs on mine and there is plenty of room for more. You can use the songs for ringtones or message tones which is also a good feature to have.
There is also a sat nav available on the phone which I find particularly handy while I am walking through unfamiliar cities.
There is an FM radio, and also an app called "Track ID" which is great when you hear a song but don't know what it is called as you can record a clip and it almost always identifies the track.
The web browser is also very useful and easy to use.
The phone does come with a few problems though (in my case anyway). The keypad can be very temperamental, I find while I am texting that when I press the # key to insert a space, it enters 4 or 5 at once and this is also the case when you try to put the phone on silent. Rather than putting it on silent, it will display a load of #'s on the screen which can get really frustrating if you are in a rush!
Also, it occasionally fails to read the SD Card inside the phone. One minute, you will get a call or text with the personal tone you set (i.e. a song) and literally the next, it will go back to the standard tone set on the phone when you first buy it. Why this is I do not know and the only way to solve it is to eject the card, blow it and put it back in the phone.
