The iOS public beta 3 came out only last week, and Apple has already launched public beta 4. Registered public beta program user can, at present, get the iOS update. iOS 10 public beta 4 offers the same features as iOS 10 beta 5.Installing the beta version is pretty easy. If you’ve already registered, then all you’ll need to do is head to Settings, then go to Software Update under General category. Like any other update, this too should appear on your screen. You just need to follow the simple instructions.For people who haven’t enrolled in the public beta program, they need to head here and sign up with your Apple ID. Then download the profile on your iPhone or iPad by following the instructions on the screen. Following this you’ll have to head to Settings and then go to Software Update under General category.Users can revert to the latest version of iOS 9.3.x if you’re not happy with it. We believe the final version of iOS 10 should be released at some point in September after Apple unveils the iPhone 7/iPhone 6SE. Recently a 4K video emerged online that showed three variants of iPhone 7. It could be a hint of confirmation of the existence of the alleged iPhone 7 Plus and iPhone 7 Pro.The videos were originally posted to YouTube by Bshop Kuwa and they showcased a 4.7-inch gold iPhone, 5.5-inch rose gold iPhone Plus and 5.5-inch silver iPhone 7 Pro. The iPhone Plus is likely to come with a single-lens camera while the iPhone 7 Pro will have a dual-lens camera.But the news isn’t official. It isn’t a confirmation that Apple is bringing out three variants of Apple iPhone 7. A couple of weeks back the famous tipster Evan Bass said that there are going to be only two iPhone 7 models. “The 2 (two!) 2016 iPhone models are codenamed Sonora and Dos Palos”, Blass wrote.
