I couldn't find any hard proof of this but I have seen (on blogs and forums) that Bank of America will charge penalty fees for closing any account before 6 months or 180 days. I also found a user who disputed that saying that he closed his accounts right after he received his bonus money, though he did not elaborate.

You should also be aware that BoA's checking accounts carry fees unless you opened a basic checking (called MyAccess Checking) and have Direct Deposit. Of course, fees will reduce your benefit from the bonus offer.
