They did update last night about 3am pacific time. I personally think they are updating every or most of every night.
Do not go by what you hear, according to those people there were supposed to be NO deposits until the 28th.. I guess the IRS proved that "Theory" wrong too.
I had one IRS agent tell me mine was deposited on the 21rst.. Called my bank to raise hell.. called the IRS back and the damn agent that I had read it wrong and there was no deposit yet..
Always double check anything that is told to you and don't put in stone anything you hear from what you ask.
Hope this helps, I am going by what I have been told and what really happened.
