On 16th March 2012, AT&T Wireless Mobiles informed that over 250 million new iPads were sold on that very Friday itself (16th March 2012). This means that the new iPad has really got people attracted towards it. The selling of 250 million new iPads reported by AT&T Services means this value is only valid for the 4G LTE (only in US, its available as 3G in other parts of the world) and not for WiFi only models. Therefore, the number of new iPads sold will be more than 250 million.
Other Wireless Mobile Service companies like Verizon, Sprint and T-Mobile are yet to give the report on the number of new iPads sold.
