Just ahead of Apple’s international launch of the iPad 2, replenishment of U.S. inventory appears to be incoming. BGR has confirmed with various Apple Store and third-party retailer locations that new shipments have begun to arrive over the past few days. Retailers we have spoken with in the New YorkÂ metropolitanÂ area appear to be receiving new units in very small quantities, and Wi-Fi iPad 2 tablets seem much easier to come by than 3G-enabled units. Apple’s online store also adjusted its shipping estimates for new orders down to 3-4 weeks from 4-5 weeks. While the short supply has lead many to believe Apple’s new iPad 2 is selling quite well, the company still hasn’t announced any sales figures.
