U.S customers who plan to order the Apple iPad 3G versions will have to wait until May 7 for their iPad as Apple is struggling to match the supply of iPads to the huge demand for the tablet. However, buyers who had ordered before April 19 will get their iPads by the end of the month, Apple has announced.
The 3G version provides access to Wi-Fi networks, as well as helps users to connect to the Internet with mobile phone carriers' service. The initial model runs only on Wi-Fi networks. Apple has sold approximately 500,000 iPads within one week of its launch.
