I put in a deposit request from my bank (bofa bastards) on 8/4 and it's still processing.
they might just have gotten cautious ... the longer they delay releasing the funds the better the chance that fraud will be detected while they still have control of the money.
today would be the second business day after you made your transaction -- ACH *from* a bank is going to be third business day minimum.
dwolla's solution lies with fisync, but only a few banks are using it or looking at using it even, for now.
