Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Apple Starts Shipping iPads to Customers
Apple has starting shipping iPads for delivery. Those who placed their orders in on the first day have started receiving shipping notices from the Apple Store.
Unfortunately, the early ship date does not necessarily mean that customers will receive their iPads before April 3rd. In the past, Apple has coordinated with UPS to hold early deliveries until launch day. The first Wi-Fi only iPads are to be delivered on April 3rd, 2010. 3G models will arrive several weeks later.
