Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
AT&T Expands FaceTime Over Cellular Support to All Tiered Data Plans
When FaceTime over Cellular launched in September 2012, we explained that we wanted to roll it out gradually to ensure the service had minimal impact on the mobile experience for all of our customers.AT&T says the update should be automatically applied over the next few months, and eligible users won't need to do anything special to begin using FaceTime over cellular.
As a result of ongoing testing, we’re announcing AT&T will enable FaceTime over Cellular at no extra charge for customers with any tiered data plan using a compatible iOS device.
This means iPhone 4S customers with tiered plans will be able to make FaceTime calls over the AT&T cellular network. AT&T previously made FaceTime over Cellular available to customers with a Mobile Share plan and those with an LTE device on tiered plans.
The upshot is that any AT&T customer with a supported device -- the iPhone 4S and newer, the third generation iPad and newer, and the iPad mini -- will soon be able to use FaceTime over cellular.
