In the end I went for a Experia Mini which I was happy enough with it until I started having overheating problems and its basically been in the repair shop for 2 months having only bought it in feb. Its a widely reported problem with the phone. So beware.
I ended up with a Samsung ch@t 222 because it was very cheap took dual sims, has radio and mp3 and a usb charger, memory slot and a 3.5mm jack. Feature wise its great. SQ is very average. But passable if you had nothing else. one nice feature is the radio presets to the number pad for fast switching between stations.
