Apple isn’t about to leave people to speculate on the number of iPads sold over the weekend. According to a press release from Cupertino, Calif., today, Apple sold more than 300,000 iPads in the U.S. as of midnight Saturday, April 3. The sales included deliveries of pre-ordered iPads to customers, deliveries to channel partners and sales at Apple retail stores.

Additionally, Apple said that iPad users downloaded more than 1 million apps from Apple’s App Store and more than 250,000 ebooks from its iBookstore during the first day.

“It feels great to have the iPad launched into the world – it’s going to be a game changer,” said Apple CEO Steve Jobs in a statement. “iPad users, on average, downloaded more than three apps and close to one book within hours of unpacking their new iPad.”

Apparently iPads are still available as of this morning. A sales representative from Apple’s New York City location at Fifth Avenue said that store still had 32GB and 64GB Wi-Fi models in stock.

Analysts’ estimates hovered right around 700,000 iPad units sold during the whole weekend. Sales forecasts for 2010 ranged from between 5.5 million and 7.1 million units.
