Cuptertino, Calif. - Consumers in five countries, including the U.S., yesterday preordered more than 600,000 iPhone 4 smartphones, exceeding any previous single day of iPhone preorders, the company said.
The unexpectedly high volume, Apple admitted, caused Apple and carriers to suffer "many order and approval system malfunctions."
The iPhone 4 became available for preordering yesterday, June 15, in the U.S., France, Germany, Japan and the U.K.
"Many customers were turned away or abandoned the process in frustration," the company continued. "We apologize to everyone who encountered difficulties and hope that they will try again or visit an Apple or carrier store once the iPhone 4 is in stock."
The first-day volume, Apple said, "was far higher than we anticipated."
For its part, AT&T said its pre-order sales on Tuesday were 10 times higher than they were for the first day of iPhone 3G S preordering.
