Windows 10 Mobile has finally arrived, Apple engineers are in it to win it, Nintendo releases its first mobile app, Nike releases self-tying sneakers, and Improv Everywhere reveal the secret of time travel.

Windows 10 Mobile Is Finally Here

Microsoft has finally started rolling out Windows 10 Mobile to handsets currently running Windows Phone 8.1. Windows 10 Mobile was originally announced a year ago, but it has until now only been available on new handsets -- such as the Lumia 950 and 950 XL -- which has shipped with it already installed.

In December, the release of Windows 10 Mobile to Windows Phone devices was delayed until "early 2016," and it is now rolling out to compatible devices. This isn't every Windows Phone device, with 18 handsets being supported. Microsoft has explained why this is the case, stating:

"As Windows 10 delivers significant new innovations, many older devices are not able to successfully upgrade without an impact on the customer experience. Our goal is to only offer the Windows 10 upgrade to devices that we are confident can continue to deliver a good customer experience."

If you own a compatible Windows Phone device you should download the Windows 10 Upgrade Advisor app from the Windows Store and follow the steps detailed within.

According to Microsoft, you should also plug your phone in to the mains, connect it to WiFi, backup all of your settings and content, and ensure you have enough space free to install the update. And then hope it all goes according to plan. This is Microsoft, after all.

Apple Refuses to Budge on Encryption

Apple is resolutely refusing to budge in its ongoing fight with the FBI over the encryption of iPhones. For those not up to speed on the story, the Federal Bureau of Investigation (FBI) wants Apple to build a backdoor into the iPhone in order to access the information on the iPhone of San Bernardino gunman Syed Rizwan Farook. Apple is refusing to comply, fearing this will be used for more than just its intended purpose.

The two sides are currently battling it out in court, but The New York Times has identified another possible wrinkle in the FBI's plans: Apple's engineers. They are reportedly already discussing what they would do if asked to circumvent the device's encryption to help law enforcement authorities. Some say they will refuse to do so, while others are threatening to quit altogether.

Apple's lawyers have even referenced this attitude in legal documents, stating, "Such conscription is fundamentally offensive to Apple's core principles and would pose a severe threat to the autonomy of Apple and its engineers". Apple clearly feels so strongly about this issue it's willing to stake the reputations of its engineers on the outcome. And the engineers who made the iPhone so secure in the first place aren't budging.

Nintendo Debuts First Mobile App

As we predicted in October 2015, Nintendo has released its first ever smartphone app, a social game called Miitomo [Broken URL Removed], in Japan. Miitomo lets you create a Mii (a cartoon avatar first seen on the Wii) of yourself, with a range of facial features, hairstyles, and outfits to choose from. You can also buy more outfits using Miitomo coins, which you can either earn as you play or pay for with real money.

Unlike the Miis that populated the Wii, the ones in Miitomo venture out into a virtual world armed with a collection of pre-recorded answers to questions such as, "What TV show are you watching?" You can also insert your Mii into photos or play the Miitomo mini-game. Miitomo is available on Android and on iOS in Japan right now, with a U.S. release to follow.

Nike Releases Self-Lacing Sneakers

Ever since Back to the Future II gave us all a glimpse into the future (now past), we have wanted a pair of self-lacing sneakers. Unfortunately, the Back to the Future-style Nike Mags aren't meant for the likes of you and I. However, Nike hasn't forgotten about us proles.

Nike has now unveiled the HyperAdapt 1.0, adaptive lacing which senses when the wearer has inserted their feet. At which point the laces tighten. The wearer can then adjust them as they see fit.

The HyperAdapt 1.0 is set to be released in time for the holidays, but only for Nike+ members. The price has yet to be revealed, so think high so as not to be disappointed.

The Time Travelling Twin Prank

And finally, time travel is such an evocative subject it's pretty much perfect as the basis for a prank. Which is exactly why this time travelling twin prank by Improv Everywhere works so well. As the title clearly suggests, this prank relies on twins to make people believe in the unbelievable.

It's a good prank, but I don't think it would have fooled me. Especially as it all played out on the New York Subway, which hardly the most suitable location for a revelation as momentous as time travel being real.

Having said that, I'm not sure what I'm expecting… maybe Bill and Ted's Excellent Adventure to turn out to be a documentary.
