In an announcement on Tuesday, T-Mobile said it had launched the world’s first standalone 5G network. It even celebrated the landmark with drone-powered light display.

To celebrate the milestone and the arrival of 5G for the first time in hundreds of small towns across America, T-Mobile used drones to light up the sky over Lisbon, ND, letting people in the small town know “5G is here”. The Un-carrier plans similar celebrations in the future… “Since Sprint became part of T-Mobile, we’ve been rapidly combining networks for a supercharged Un-carrier while expanding our nationwide 5G footprint, and today we take a massive step into the future with standalone 5G architecture,” said Neville Ray, President of Technology at T-Mobile. “This is where it gets interesting, opening the door for massive innovation in this country — and while the other guys continue to play catch up, we’ll keep growing the world’s most advanced 5G network.”

Today, Apple unveiled an updated 27-inch iMac. Over on Six Colors, Jason Snell asks the question many of us are undoubtedly pondering – is this the last Intel-based iMac. (I agree with Jason that the answer is probably yes.)

As for the future, is this the last Intel Mac we’ll see? There’s no way to tell, though reading between the lines, it wouldn’t be surprising if there were some more Intel-based Mac releases as Apple progresses through its two-year-long processor transition. But I’d wager good money that the next time we see an iMac update, there won’t be an Intel processor at its heart. And perhaps it will look appreciably different, too.

We’ve all needed to do some iPad troubleshooting from time to time. However, we don’t normally need to do it whilst also helping a spacecraft land. However, that’s what happened on the latest SpaceX trip, reported Space Explored.

The communication started with Astronaut Behnken explaining that he had an issue with something before communication dropped out momentarily. A few seconds later, the astronaut read out an error message presumably from the custom SpaceX application created for the iPad. “A timeline application on my tablet, uh, gives me a error message that says Safari cannot open the page, and then it’s got a HTML address because your iPad is not connected to the internet,” Behnken reported. “Can you confirm that Wi-Fi is off and AirPlane Mode is on,” asked Menon. Then the NASA astronaut improvised with a go-to troubleshooting step. “Yes, uh, Wi-Fi is off and AirPlane Mode is on. If you have the display cameras up, I’ll try to show it to you,” Behnken suggested. “We will take that,” Menon replied. “We’re coming up on a ground station pass and we have the display camera up.”

Recent market moves have made Warren Buffett’s AAPL holding worth over $100 billion after tripling in value. Business Insider broke it down.

250 million Apple shares between 2016 and 2018, according to his 2019 shareholder letter. Buffett has cashed out some of that holding since then, and owned 245 million shares at last count. The position is currently worth more than $104 billion. Apple’s third-quarter earnings sent its stock price up 10% to an all-time high of $425 on Friday, lifting its market capitalization to north of $1.8 trillion, and making it the most valuable company on the planet. Apple stock has climbed about 42% this year, boosting the value of Buffett’s stake by $30 billion in the past seven months alone.
