I have not. Would have to do more research. What did he do exactly?
Regarding Miltiades you clearly know much more about all of this than I do, and your reasons for excluding him are fair, although I would point out that, regardless of what it says about political ability or the significance of a battle, the Athenians in general seem to have been all too willing to make enemies of their heroes, considering the fates of Themistocles, Alcibiades and the admirals at Arginousai.
As for Iphicrates, one might summarize his career as follows:
1. Late 390s/early 380s: He was perhaps Athens' most successful general in the Corinthian War, campaigning as a general and admiral in the Peloponnese and the Chersonese, and winning several important battles against the Lacedaemonians and their allies including the aforementioned battle against the Spartiates at Lechaeum (post 511), the battle where he defeated the Spartan general Anaxibius in a defile near Abydos (post 510), the ambush of Anaxibius (thereby killing Anaxibius and wresting control of the Chersonese: post 510), the battle in which he seized the Lacademonian camp while they were foraging (post 510), and his defeat of the Chians (post 510).
2. Late 380s: He successfully campaigned for Athens in Thrace, restoring Seuthes to his throne. This campaign included a notable ambush of the Thracian army by Iphicrates, and presumably the incident in which he used Thracian prisoners to defend against Thracian skirmishers (post 510).
3. Early 370s: He campaigned in Egypt as a mercenary general on behalf of the Persians.
4. Early 370s?: He reformed his hoplites in a manner that constituted a precursor to the Macedonian phalangite (Philip II notably spent time with Iphicrates when he was in exile from Macedon)
5. Late 370s: He relieved Corcyra from a Lacedaemonian siege and defeated the Syracusan reinforcements.
6. Late 370s or early 360s (I don't remember): He fought against a Theban invasion of the Peloponnese. I seem to recall reading that Epaminondas avoided doing battle with him (if he was as tricky as those anecdotes in post 510 indicate, I don't blame him).
7. 360s: Iphicrates sides with his marriage relation, Cotys of Thrace, against the Athenians.
8. 350s: Having been pardoned by Athens, he commands a fleet for them in the Social War. After he and two of his colleagues refuse to go into battle during a severe storm, he is impeached by the one admiral who did and was defeated in battle, Chares. Iphicrates is acquitted after he gives a speech while holding a sword and has armed mercenaries among the audience.
9. In general: Having enjoyed a forty-year military career, his numerous tactical feats were sufficiently notable that Frontinus and Polyaenus include numerous anecdotes about him in their volumes on military tactics. The anecdotes included in post 510 are only a few highlights. He was also spoken of as a great general by Xenophon and Nepos. Nepos,
Iphicrates 1: '...he was such a leader, that he was not only comparable to the first commanders of his own time, but no one even of the older generals could be set above him. He was much engaged in the field; he often had the command of armies; he never miscarried in an undertaking by his own fault; he was always eminent for invention, and such was his excellence in it, that he not only introduced much that was new into the military art, but made many improvements in what existed before.'
