Firmware: R1JC002 JP-7.3
This phone was one of the first great SonyEricsson feature phones with SonyEricsson's new JP-X software stack. Slim and works great.
The keypad is a little annoying but workable.
This phone doesn't suck, unless you get a Vodfone UK-crippled one that has root certificates removed and so won't install 3rd party software.
