Multiple online sources, including the New York Times’ Gadgetwise blog, are reporting that new information has appeared today on the US Apple Online Store, denoting that the three 3G models will ship to customers “By May 7th”, which marks a slight delay from the end-of-April release date that was previously tagged to pre-orders. The 16GB Wi-Fi + 3G model is available for pre-order for $629.00, the 32GB Wi-Fi + 3G model for $729.00, and the 64GB Wi-Fi + 3G model for $829.00. Shipping for all models is free. Customers have a choice of two monthly data plans from AT&T – 250MB or unlimited. You can sign up for a contract-free data plan and change your service directly from your iPad if you so desire. AT&T data plans also include unlimited access to over 20,000 Wi-Fi hotspots at locations such as Starbucks and Barnes & Noble. ** Update, for those that pre-ordered the iPad 3G before today, you should still receive it by the end of the month according to recent emails sent out by Apple!
