Answer:
The answer is Apr. 3
Explanation:
Preorders began on March 12, 2010 ahead of an Apr. 3 U.S. release date at Apple's online and outlet stores. Initially, only Wi-Fi models were available — 3G-capable models had to wait until Apr. 30, and then could only be used with AT&T in either unlimited or 250-megabyte plans.
Apple put the iPad on sale for the first time on Apr. 3, 2010 and ended up selling over 300,000 units in just one day.
