The best bank account for unemployed people?

I have become unemployed and consequently fallen behind with all my credit card debts. I am considering bankruptcy but have been put off this by people saying that they freeze your bank account once they hear you have declared yourself bankrupt. As I am unemployed, I was just wondering what would be the best bank to approach for just a basic account, should I go down the route of bankruptcy and my two current banks close my accounts down. The two accounts I have are: Halifax basic bank account, and Barclays Savings Account.
