I tried and failed today. After the account was open, I'd deposited $500 (cold hard cash), signed the disclosures, etc -- then, and only then, the banker put in my coupon code and the computer said that I'd already received the offer for this year. So, I had her cancel the account and refund my deposit (I accepted paper money for the refund).
Oh well. I also paid off my BA credit card with cold hard cash while I was there, so at least that was good.
For reference, I had opened my last checking accounts the last week of December 2009 and met the reward requirements in January 2010 -- that counts as a 2010 reward.
