LOS ANGELES. Sales of Apple’s latest iPhone blew away expectations in its first day on the market despite shortages and an embarrassing online ordering glitch that thwarted many shoppers.

 

Apple shares rose nearly 3 percent yesterday after it announced sales of more than 600,000 iPhone 4s, a record for just a single day of pre-orders.

 

But Apple apologized for having to halt sales after the surprising volume of online interest overloaded order and approval systems and supplies ran out. AT&T, the phone’s exclusive U.S. carrier, said that sales will resume as soon as inventory becomes available.
