Apple will have its Second Quarter results conference call this Wednesday, April 23, 2008, 2:00 p.m. PDT/5:00 p.m. EDT. Apple will, as always provide a live audio stream of the call which you will be able to access here.
Before the actual call, Apple will release the numbers via a press release, but it is sometimes still interesting to see what gets discussed on these earnings calls.
