Companies filing for bankruptcy?

I would like to find a website or database, list or maybe an app for my Iphone with information about companies filing bankruptcy that trade publicly in the stock market.

They have to make SEC declaration

Federal bankruptcy laws govern how companies go out of business or recover from crippling debt. A bankrupt company, the "debtor," might use Chapter 11 of the Bankruptcy Code to "reorganize" its business and try to become profitable again. Management continues to run the day-to-day business operations but all significant business decisions must be approved by a bankruptcy court.

Under Chapter 7, the company stops all operations and goes completely out of business. A trustee is appointed to "liquidate" (sell) the company's assets and the money is used to pay off the debt, which may include debts to creditors and investors.
