My credit must be getting better

In May I wanted to see if I could get another credit card to expand my credit growth. I applied for a Circuit City Credit card. At first, when I applied online, they told me that they can't approve it now but they will contact me for some confirmations, blah blah blah. I thought, "what ever, they're not going to give it to me". Two days later I get a call from Circuit City credit department, they confirmed my address and my business name and told me I now have been accepted and gave me $1000 credit with Circuit City.

Awesome!! So now I have $1300 available credit that I can work with. The plan is just as it was before, have about 1/3 of the credit used and make payments on it. This should get my credit score up.
