“Apple’s iDay will put a $200 million revenue ka-ching on the end of this quarter,” Scott Moritz reports for TheStreet.com.

“The temps are trained, crowd control measures are in place and the stage is all set for Friday’s debut of the huge iPhone. If Apple can pull it all off, this most orchestrated of product introductions should manage to move nearly 400,000 phones out the door on the first day,” Moritz reports.

“Follow this math: There are 162 Apple stores and 1,800 AT&T shops — so exactly 1,962 sales outlets will be pushing the iPhone,” Moritz reports. “The current rumor is that each store is being rationed somewhere between 100 to 250 phones.” Sales will begin at 6pm and end at 10pm local time across the U.S.

“All the campers, long-line sitters and the rest of the willfully determined soon-to-be iPhone owners will likely clean out the shelves in the allotted time. That, of course, assumes that each sale takes 10 minutes or less, and that each store has at least eight clerks ringing the register,” Moritz reports.

“So with 1,962 stores and let’s say 200 phones per store, Apple stands to sell some 392,000 iPhones, I can now reveal,” Moritz reports. “With each phone selling for an average price of $550, Apple stands to take in $216 million in revenue on the evening of June 29. And that’s not including online sales.”
