iPad 2 Shipping Estimates for U.S. Online Orders Improve to 3-4 Weeks

Just hours after the first international online orders for the iPad 2 began with shipping estimates of 2-3 weeks, Apple has shortened estimates for new U.S. orders to 3-4 weeks from the earlier 4-5 week figure that has been in place for nearly ten days.

Reports from MacRumors readers have indicated that shipments of earlier iPad 2 orders are beginning to come through in larger quantities, and we're hearing of more stock making its way to Apple's retail stores, suggesting that supply constraints may be starting to ease just in time for the international launches.
