There's nothing to be gained by continuing in limbo, not knowing if your application is still under consideration. Personally, I wonder if working for an organisation that is impolite/disorganised enough to leave you in this uninformed state would be a good career move.
Contact them and ask what the status quo is.
I say contact them as well. Some places the only way to get hired is to bug the heck out of them. I know locally one employer is like this. If you want to work for the state here you have to keep hounding them to get them to do anything regarding hiring.
