FaceTime Over Cellular to Be Limited to the New iPad and iPhone 4S
Unfortunately, another feature of iOS 6 that has been widely looked forward to will be limited to only Apple's newer devices. FaceTime over cellular networks seems to only be coming to the new iPad and the iPhone 4S. In what seems like a desperate attempt by Apple to keep people upgrading to newer devices every year, FaceTime over cellular networks will join Siri and Maps' new turn-by-turn directions as an iPhone 4S and new iPad-only feature regardless of older devices such as the iPhone 4 being capable of the features.
The iPad 2 joins the party with the iPhone 4 in FaceTime-capable devices that won't be getting the 'over cellular' feature in iOS 6 even though it has an A5 processor. The iPod touch 4G never had cellular service from the beginning, so it is not much of a surprise that this device isn't getting the feature.
Although the news is a letdown for people owning older iOS devices, anyone with the newer iOS devices like the new iPad and the iPhone 4S should be happy knowing that they will have the feature. Older devices will have to wait for a jailbreak-based solution to get FaceTime over cellular networks. As an alternative, an older device could tether (or share a cellular connection) with any other tethering-enabled iOS device to use FaceTime from anywhere without a jailbreak.
Most older iOS device users will be able to make do with third-party FaceTime alternatives such as Skype and Tango as they are widely used by iOS users. Additionally, users can still use Wi-Fi as usual.
