Are you are stuck on iOS 10.2.1 or higher, having missed the iOS 10.2 signing window and therefore the Yalu jailbreak? If so, you may be in luck today, provided you have the correct setup. Early reports have come in that some devices are creating nonce collisions on iOS 10.3 b1, providing an indirect route back to iOS 10.2 through Prometheus.
For this clever workaround to come off, you must have a device which produces collisions, namely the iPhone 5s or (possibly, though not confirmed on iOS 10.3 b1), an iPad Air. If you do, you may be able to downgrade from iOS 10.2.1 to iOS 10.2 and jailbreak, by first downloading and installing iOS 10.3 beta 1, and then downgrading to iOS 10.2 using futurerestore.
A beta of iOS 10.3 that was seeded to developers last week comes with an updated app compatibility warning which cautions users that 32-bit apps may no longer work with future iOS versions, suggesting iOS 11 will likely stop supporting non-64-bit apps. In June 2015, Apple warned developers that all apps and app updates submitted to App Store must include 64-bit support alongside 32-bit code.
When a user launches a 32-bit app, iOS 9 puts up a warning saying using 32-bit software on a 64-bit device may affect system performance. The wording of the prompt has changed in iOS 10.3 beta 1 and now specifically states that 32-bit apps may stop functioning on future iOS editions completely.
Another hidden keyboard has been uncovered in iOS, according to developer Steve Troughton-Smith who last night tweeted about his discovery of a one-handed floating iPad keyboard in iOS 10.3 beta code.
While not exposed to users just yet, Steve was able to activate this new keyboard by hacking Apple's iOS Simulator app that developers use to test work-in-progress code on their Mac.
Following yesterday's release of developer-only previews of the upcoming iOS 10.3 and macOS Sierra 10.12.4 software updates, Apple today made the new betas available to public beta testers who are enrolled in Apple Beta Software Program.
iOS 10.3 public beta can be installed via the Software Update mechanism on iOS devices with an appropriate configuration profile installed. macOS Sierra 10.12.4 public beta can be downloaded on your Mac through Mac App Store's Updates tab.
U.S. wireless carriers like AT&T, Verizon, Sprint and T-Mobile have supported Wi-Fi Calling for some time now, with AT&T, Sprint and T-Mobile also supporting Wi-Fi Calling on other iCloud-connected devices like iPad, iPod touch, Apple Watch and Mac. According to user reports on MacRumors' forums, iOS 10.3 beta 1 supports Integrated Calling on Verizon.
With this handy feature, compatible iCloud-signed devices can make and receive calls using your carrier's account even when your iPhone isn't nearby.
Apple today seeded the first beta of what would become the third major software update to iOS 10 since its September 2016 release. The release includes a new Find My AirPods feature and other enhancements, like Reduce Motion for websites.
iOS 10.3 beta 1 (build 14E5230e) is available to registered developers who are members of Apple Developer Program. A version of the software aimed at public beta testers registered with Apple Beta Software Program is expected shortly.
