Some parts of iOS 6 require the 4S -- turn-by-turn navigation, for instance -- or either the 4 or the 4S, such as Safari's offline reading list.
Who gets the iPhone 5 first? Customers in the U.S., Australia, Canada, France, Germany, Hong Kong, Japan, Singapore and the U.K. can purchase the iPhone 5 on Sept. 21. (That list is the same as last year, with the addition of Hong Kong and Singapore.) Twenty-two other countries -- the list is in this press release -- will follow on Sept. 28.
Still more will get the iPhone 5 in December, Apple said Wednesday: It's goal is to have the new smartphone in a total of 100 countries by that month. No word yet on what those markets will be, and on what schedule.
"This will be our fastest iPhone roll-out ever," said Apple's head of marketing, Philip Schiller. My wallet's as thin as possum road kill on I-20, but I still want an iPhone ... what are my options? Apple again dropped the price of last year's model -- this time it's the iPhone 4S -- to $99. The half-off iPhone 4S is a 16GB device, twice the storage capacity of the $99 iPhone 4 Apple offered last year.
Apple's also retained its now-two-year-old device, an 8GB iPhone 4, which will be free at the register or online checkout. Okay, not really free, not by a long shot: Like any subsidized iPhone, buyers have to sign a two-year contract with a carrier.
The new, reduced prices were effective immediately; Apple's U.S. online store now shows both the $99 iPhone 4S and the free iPhone 4 as shipping in "1-2 business days" after ordering.
