Iran claims the launch as being successful.

http://www.presstv.ir/Detail/2017/07/27/529852/Iran-successfully-tests-Simorgh-satellite-carrier

Videos attached. I've corrected the aspect ratio of the second video.

This report says the vehicle did not put a satellite into orbit. Bing translation.

"Shahrabi said in this regard: Although the launch yesterday, did not put a satellite in orbit but in the distant future a system of 40 to 160 to satellite remote sensing, telecommunications and positioning in the circuit."

Has NORAD published 2 line elements for the 2nd stage, or was this a suborbital test? If so, how does Iran monitor 2nd stage performance?

According to news reports today, Pentagon Officials have declared this a catastrophic failure; nothing achieved orbit, so no TLEs were published by 18SPCS.

Judging by the speed at which it jumped off the pas it must have had a pretty high t/w, might just indicate dummy or unfueled upper stages.

I know I'm slightly out of subject, but Ed Kyle can you indicate us why you do not count this launch attempt as an orbital attempt in spacelaunchreport?

Now we know this was, with a high degree of certainty, a failure. But the iranian government clearly indicated it was an orbital launch.
I would probably treat it like the rocket lab first shot, don't you think?

Insufficient information.  I disagree with the assertion that "the Iranian government clearly indicated ..."  See up-thread discussion about how it was called an "orbital capable" launch vehicle, but no mention of a specific payload, etc, or even that it was a real orbital attempt.  I'll add it later if better information is provided one day.  Too much disinformation from both inside and outside Iran right now.  If it was an orbital attempt, it failed as claimed by U.S. sources.  If not, it may or may not have been a suborbital test failure.

 - Ed Kyle

Very valid reason indeed.
My own view on the matter (not that it should weight for something) is that it was the Sharif orbital remote sensing satellite, presented earlier in the year with Amirkabir and Nahid sats. Knowing this was a failure, state has declared it was a success for the public but didn't mention the sat as it was destroyed.
We probably won't know more before a few months when they will speak about the next launch attempt.

Iran has never release footage of a failed orbital launch so far. This is a strong hint, that this launch was not a failure. Therefore IMHO this was a successful suborbital launch. Note, that in translations from Farsi, there was often a mixup between "space" and "orbital".

Because they also say that Iran has never launched a satellite.

Given the fact iran released pictures and video of this launch it is probable that this was in fact a suborbital launch. Also cant help but notice the remarkable design similarities this rocket has with NK's Unha-2 rocket.

What is that orange smoke?.
Are turbopumps in the upper part of the second stage?.

That shows the second stage being integrated horizontally, but the other image shows the first stage being lifted vertically, with presumably the second stage being integrated vertically.

Because if what they were reporting about *this* event wasn't accurate, I wouldn't have sourced it.  I have already contacted the author with corrections to a misstatement made by their source that was used in 3 or 4 related articles.  They will publish a correction.  It seems pretty foolish to dismiss the report out of hand simply because it came from the most widely trusted newsource in the country... you're letting politics spoil your objectivity.
