"A great phone that suffers from a terrible fragile Keyboard and it's battery cover is so flimsy- you will feel let down by Sony on inspection. Not Robust-Not a Solid Build. It makes good quality calls- the walkman player sounds good with a nice looking interface. Battery life is no where near as high as in any press release nor in the manual for this model. The slide mechanism is well designed. Sonys bundled Pc software is reliable and the phone does also double as an HSDPA modem (if your network supports this) with very reliable connection. As long as you can stand the massive "lego brick" style adaptors to connect headphones- a very poor fragile keyboard,Then get it. Not a phone for people who use thier mobiles for voicecalls everyday. It's more a cheap walkman with a phone in it somewhere. Camera is dire."
