Anyone think of the perfect phone for my sister?

So my sister is looking for a phone that is not too big so the screen is no bigger than 3.7 inches, she also wants it to be good for putting around a 800 songs on and the music player to be easy to use. The rest are pretty basic a simple web browser and a T9 keyboard. She also is not too bothered about getting the latest update. I suggested to her to look at something like the Lumia 800 or HTC Radar

What are your suggestions? (Bear in mind I'm in the UK)
