Credit Card Arbitrage - Update

The process is complete and I am now earning 4.75% on $6,500 thanks to Citi Bank. I received my Citi Bank credit card a week and a half ago and immediately requested a check from their website. The check arrived a few days later and now has been transferred to my savings account with ING. The process went smoother than I expected, so I am going to try this arbitrage thing once more. This time my wife will be applying for the card. I will post once everything is set up with that account.
