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 Cuperti** company's new flagship smartphones. While it's unk**wn 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.
