Apple will introduce new versions of iOS and OS X at its annual developer's conference.
New International iPhone 4S Pre-Orders Through Apple Slip to 1-2 Week Shipping
Current shipping estimates in Apple's Canadian online store
Apple and its carrier partners began pre-orders around midnight Pacific Time, although Apple's and AT&T's sites didn't come up for orders until about 40 minutes after the scheduled launch time. And even after pre-orders came up on Apple's site, users had significant difficulty getting through. Much of the bottleneck appeared to be related to verifying eligibility and plans through AT&T, with the purchasing process repeatedly hanging and resulting in errors for many users.
iPhone 4S reservation issued due to problems with carrier processing
Apple eventually shut down its iPhone pre-order system for a brief period of time, bringing it back up to issue reservations that would allow users to return later to verify eligibility and select their service plans. Apple has begun notifying users who placed early reservations that they may now return to apple.com to complete their orders, and that they must complete the process by 5:00 PM Pacific Time tomorrow in order maintain their priority order status.
