In a large skillet heat oil over medium heat. Add the drained corn. Cook, stirring occasionally until a few kernels take on some color. Scrape corn into a large mixing bowl and allow to cool to room temperature.
In a small bowl stir together sour cream and the rest of the ingredients except the garnishes. Pour over the corn and mix well.
Refrigerate for an hour or two at least to allow flavors to meld. Serve chilled, at room temperature (recommended), or slightly warm. Garnish with more cilantro and lime wedges.
