Apple will introduce new versions of iOS and OS X at its annual developer's conference.
T-Mobile and Sprint to Start Selling Apple Watch on September 25
With the iPhone 6s and 6 Plus launching on September 25, it's likely carriers want the ability to sell Apple's smartwatch as an accessory to the Cupertino company's new flagship smartphones. While it's unknown whether Verizon and AT&T will also sell Apple Watch on September 25, it's possible they will also sell the device.
Since launching in April, the Apple Watch has slowly been expanding to retailers like Best Buy in the U.S. and other countries. Initially, Apple Watch was limited to Apple Stores and select retail boutiques.
Update: Sprint has confirmed it will begin selling the Apple Watch on September 25.
