While he was trapped, a time traveler appeared at one point and killed a man named Charles Xavier.
Through means unknown, this Captain America was freed from the Red Skull's trap. However, he awoke to find the world ravaged by a war between mutants and humans as there was never anyone who led the mutants in peace. He chose to abandon his iconic American themed uniformed for one of grey, red, and gold.
Captain America's appearance was merely a cameo with no speaking part.
In the Comics
Apparently, there is no Captain America in the Age of Apocalypse universe (a backup text in Universe-X implies that he's still frozen). He does exist in a What If? version where he leads the Defenders along with Wolverine, Sauron, Captain Britain, Brother Voodoo, Colossus, The Thing, Molecule Man, and Nate Summers.
