Preview at WWDC likely in June, followed by September launch.
AT&T's 'Mobile Share' Service Plans Launching August 23
AT&T has just announced that the new plans will be launching on August 23, and while current users will not have to switch to the new plans, they may do so without adding on to their contract term. And unlike Verizon, AT&T will continue to offer its existing plans alongside the new Mobile Share plans, giving users several options to help fit their device and service needs.
AT&T's new Mobile Share plans do include tethering and mobile hotspot functionality on compatible devices, while also offering free access to over 30,000 AT&T Wi-Fi hotspots around the country.
Full details on the new plans are available on AT&T's website.
