The border crossing is open for passage 24 hours each day.
The border is open 24 hours at Iguasu. but why are you overnighting in Argentina when you're flying out by a sunrise flight from Brazil? The sensible thing to do is overnight your last night in Brazil! Then you have nothing more than a 10-15 minute taxi ride to the airport.
If you overnight in Argentina, you need to find a taxi that will take you to Brazil. You must do passport control in both countries. Any delays or any documents not in order, and you miss your flight.
If you do the border crossing to Brazil the afternoon of the day before, you'll have the luxury of time and the opportunity to straighten out any problems. Then you don't have to get up nearly as early in Brazil.
Here's another reason: What's the date of your flight in Brazil? If it's between October 20, 2013 and February 15, 2014, Brazil observes Davlight Saving Time while Argentina does not.
(Being from Singapore you might ask, what's Daylight Saving Time? At 12:01 midnight on Sunday, October 20, 2013, Brazilians turn their clocks ahead one hour. When it's 12:01 midnight in Argentina, it becomes 1:01 a.m. in Foz do Iguaçu, Brazil.)
Suppose you didn't know that. You'd climb into your taxi, expecting to reach the Brazilian airport IGU and depart from Brazil at 6:55. Because of the time difference, though, 6:55 in Brazil is really 5:55 according to your wristwatch, set to Argentine time. You might miss your flight, or at best have a very close call. This would not be a serious problem if you overnight in brazil, because the clocks there would warn you of the danger. You'd get no hint of the change if you're overnighting in Argentina.
Aren't you going to be seeing the Brazilian falls? Brazil gets the only panoramic view of Iguasu Falls, another reason for spending a bit of your time on the Brazilian side.
