Checks by Deutsche Bank Chris Whitmore and Piper Jaffray analyst Gene Munster this weekend suggested that Apple had sold out of iPad 2s in record time. Both checked across retailers and found that no stores had stock left by Saturday. Whitmore had the most diverse look and found the sellouts true both across 50 Apple stores, 20 Best Buy and Walmart stores, and a blend of AT&T and Verizon carrier stores.
