The 3G-capable iPad will be available in the US on April 30th, Apple has announced. Early pre-orders should be delivered as the day goes on; Apple Stores, however, will only begin selling the device at 5PM local time, in contrast with the morning launches of the Wi-Fi iPad on April 3rd. 3G models are set to cost $629 for 16GB, $729 for 32GB and $829 for 64GB.
