Here are the final estimates — barring last-minute revisions — along with each analyst’s rank, where available, in last quarter’s earnings smackdown. [UPDATED 4/18 to correct error in Sterne Agee’s estimates, 4/19 with new numbers from Turley Muller, Rodman & Renshaw and BCG Partners, and 4/20 with estimates from Bernstein and Technology Insights.]

We’ll find out whose numbers were closest to the mark when Apple releases its earnings for the second fiscal quarter of 2011 after the markets close Wednesday, April 20. A conference call with analysts is scheduled to begin at 5 p.m. EST (2 p.m. PST). The hour-long session will be webcast here.

We’ll compare the estimates to the actual results and publish the results Thursday morning.
