UPDATE: We have a winner. Apple announced Monday that the correct answer was "over four million," the guess of nearly 23% of our readers.

- - -

When the iPhone 4 went on sale 16 months ago, Apple (AAPL) sold 1.7 million in the first weekend, counting pre-orders.

The analysts who have ventured a guess seem confident that by Sunday night, iPhone 4S sales will have smashed that record, but there's considerable disagreement by how much.

Here are the predictions we've seen:

• Piper Jaffray's Gene Munster: 2.0 to 2.5 million
• RBC Capital's Mike Abramsky: nearly 3 million
• Yankee Group's Carl Howe: 4 million

What's your estimate?

• Steve Jobs' leave: Analysts weigh in - updated

  Apple's CEO, says one, is both the company's biggest asset and its biggest risk

  The U.S. financial markets were closed, but a few analysts took a break from their Martin Luther King Day remembrances to say a few words about what Steve Jobs' latest health advisory might mean to Apple (AAPL) shareholders.

  Piper Jaffray's Gene Munster treated it as a MORE

• Why Apple shares took a nosedive

  Apple shares suffered their sharpest fall in eight years Monday morning on the word of two analysts -- including one whose record predicting the company's performance is mixed at best.
