When it comes to operating system updates, a "dot-dot" release is usually reserved for bug fixes, and a "dot" release adds performance enhancements and some minor new functionality. With Apple, a full release, like 7.0 or 8.0 is a major update, often with 1,000-plus new features. True to form, Apple unleashed iOS 8.3 this week and there are just a few features worth mentioning. First, as I covered earlier, depending on your carrier (Sprint and T-Mobile in the U.S., EE in the UK), you can now make phone calls using Wi-Fi, without consuming cellular minutes or requiring a cell tower nearby. That means you could make phone calls from overseas, for free, and still appear to be calling from your cellphone number.
