Find out what the model number is then you can search for it.
Your best bet will probably be finding one on ebay that has a broken screen, they are usually not worth repairing.
How did it break? You dropped it... and you have house insurance right

Damn, this fella's good. Was about to post the same advice about finding one with a broken screen.
It's like having a written-off car because it's been in rear-end shunt and the chassis is buggered. The engine's still fine, and if there's another car with an engine that's blown up - you can make one working car out of that.
House insurance is a good call as well.
