Apple has sold out of the iPad inventory it allotted for pre-orders and the company’s Web site is now saying that every model of the new iPad will ship to customers in two to three weeks. It will begin selling the new iPad in retail stores starting Friday, which is about when the people who ordered it online will have the iPad delivered. @copy dvd movies to ipad 2

“Customer response to the new iPad has been off the charts,” said an Apple spokeswoman, Trudy Muller, adding that the product would be available on a first-come, first-served basis on Friday in Apple stores and other retail locations.

Typically, what that means for a new Apple device is long lines or, if you’re not willing to wait around in a queue, paying a healthy premium to the people who might seek to profit off the scarcity of new Apple products. On the San Francisco Bay Area Craigslist, a quick perusal of listings shows an asking price of between $650 to $800 for the cheapest new iPad model, which normally retails for $499. The people advertising on Craigslist are promising to deliver the new iPads after they receive them this week. @convert flash to mp4

The sell-out left Wall Street analysts guessing how many new iPads Apple sold since it became available for order on March 7, with Gene Munster of Piper Jaffray speculating that pre-orders exceeded one million and Ben A. Reitzes of Barclays Capital saying the figure was likely in the millions.

Apple frequently reveals first day or first weekend sale of new products, and sometimes pre-orders. In the case of the original iPad, Apple sold 300,000 during its first day on sale in April 2010. Apple sold its millionth iPad 28 days after the original went on sale.
