After making its Z Launcher open to the public in beta form last fall, Nokia has issued the first major update for the app. In this update, Nokia is laying the groundwork for icon pack support, along with various UI and design improvements.

If you store a lot of documents in iCloud Drive, and you’re on a limited data plan, you may not want apps moving large files around unless you’re on Wi-Fi. Cellular data use with iCloud Drive is nowhere nearly as intensive as streaming music or videos, but if you want to make sure not a bit goes by without your say so, you can manage it all in Settings.

How to turn cellular data on or off for iCloud Drive syncing

1. Launch the Settings app on your iPhone or iPad.
2. Tap on iCloud.
3. Tap on iCloud Drive.
4. Scroll all the way to the bottom and turn Off the option for Use Cellular Data.

Jeff Williams, senior vice president of operations at Apple, took over day-to-day leadership of the ops team following Tim Cook’s transition from Chief Operating Officer (COO) to Chief Executive Officer (CEO). Since then Apple has shipped a flabbergasting number of iPhones, a huge number of Macs and iPads, and started ramping up to ship the first batch of Apple Watches. To say Williams runs the best ops team in the business does him and them a disservice — No one else even comes close. That’s no dount why he’s getting some much-deserved attention following Apple’s blow-out Q1 2015 results. Neil Cybart, writing for Above Avalon:

One thing became abundantly clear after analyzing Apple’s recent earnings report: Jeff Williams is doing a phenomenal job. As senior vice president of Operations, Williams is tasked with making sure the Apple machine is well-oiled and in tip-top shape, not only capable of producing more than 100 million iOS devices in a quarter, but building flexibility into the system to handle annual hardware updates that would make most hardware companies quiver with fear.

John Gruber, writing for Daring Fireball:

First, in terms of iPhone operations and considering nothing else, Jeff Williams has clearly done an amazing job. Apple sold a record 74 million iPhones last quarter, and though the company doesn’t break that down by models for competitive reasons, everyone knows that a huge chunk of those were the brand-new iPhone 6 and 6 Plus. They were supply-constrained on both models, particularly the 6 Plus, but only by a few weeks. Operationally Apple did an incredible job meeting demand for iPhones — they sold more than ever but were less supply-constrained than in the last few launch quarters. For context, in 2008, Apple sold a total 10 million iPhones for the entire year. All credit to the hardware, software, and product marketing teams for the fact that 74 million people wanted to buy an iPhone last quarter. But the credit goes to Williams’s operations team that there were 74 million units available to sell.

There was a story, I believe passed along by Gruber, about how someone asked how the original iPad came to be, and the answer they got was Steve Jobs. When they asked how it came to cost only $500, the answer they got was Tim Cook. Today, Jeff Williams is running the Apple Watch team, and when it comes costing only $349, he’ll be a huge part of that answer.

Behind Tim Cook’s mantra of “making the great products” is Apple’s ability to make customers believe they’re getting value far beyond the cost. Part of that value equation, now like then, is thanks to the ops team, and at a scale that dwarfs anything else we’ve ever seen before.

For that, Jeff Williams and his entire org deserves not only a ton of attention, but ton of credit as well.
