Been in my drawer for ages. Works fine and is unlocked. No idea what it's worth, probably not a lot, not sure where the charger is but its a standard fitting. Comes with a spare battery as I bought an upgraded one to improve battery life.
We've two kicking around here. It's a dependable phone. Limited to gingerbread and its GPS is fairly battery hungry but there's an updated jelly bean look cm rom which is pretty easy to install. £13 posted seems a fair price.
