Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Apple Launches 128 GB iPad with 1-3 Day Shipping
The new model, offering double the storage capacity of the previous top-of-the-line model, carries a $100 premium over the 64 GB versions and is available in all four combinations of black/white and Wi-Fi/Wi-Fi + Cellular models.
