Well that didn't take long. After yesterday's mistaken build 14998, which confused the heck out of the Fast ring Insiders everywhere, the real build (that I predicted exactly) finally got released: 15007. There's even an announcement blog post to go with it. The good news? If you did install 14998 (like me) then you can breathe a sigh of relief, your device will still see 15007 and install it!

From Microsoft (and filtering out stuff that's explicitly for desktop/PC only):

Today we are excited to be releasing Windows 10 Insider Preview Build 15007 for PC and Mobile to Windows Insiders in the Fast ring.

What’s new in Build 15007 for PC & Mobile

More Microsoft Edge Improvements:

• Text scaling and zoom (Mobile): Based on your feedback, in Microsoft Edge you can now zoom into a webpage regardless of zoom settings defined by the website, matching other mobile browsers. Pages are now zoomable to at least 500%. Because of this, we no longer automatically scale text in Microsoft Edge when you’ve enabled the Ease of Access option to increase the text size, since you can zoom in on the text to reach a size that matches your own comfort level. This addresses feedback that Ease of Access zoom settings made web pages render incorrectly.
• Apps for Websites: Clicking links to websites that support web-to-app linking will now open that page in the respective app.

Scrollbar improvements for UWP (PC & Mobile): We have made improvements to the XAML scrollbar for mouse to ensure it is available when you need it, while taking up less space and causing less undesirable flashing when you don’t. With these changes, the panning indicator now appears when you move a mouse over a scrolling region and the full scrollbar appears when you want to directly interact with it. This improvement will be visible in any app that uses the Windows 10 Creators Update SDK.

New Bluetooth APIs (PC & Mobile): This is the first build you can try out the new APIs that enable GATT Server, Bluetooth LE Peripheral role and unpaired Bluetooth LE device connectivity. We will be flighting an updated SDK tomorrow, please look for 15003 or greater SDK.  For more information, the Windows developer blog will have post tomorrow on GATT Server once the SDK flights.

What’s new in Build 15007 for just Mobile

Sync your settings using Azure Active Directory (AAD) Identity (Mobile): You can now sync your settings on AA-Joined phones using Enterprise State Roaming. With Enterprise State Roaming enabled for your phone, you can sync settings such as passwords, Wi-Fi profiles, Edge Favorites, Edge Reading List, and app data across desktop and mobile devices. To get the most out of this feature, make sure sync is turned on for the same account on both your mobile and desktop device under Settings > Accounts > Sync Your Settings.

App reset (Mobile): One of the features added to PC with the Windows 10 Anniversary Update was the ability to reset an app back to its original state. We’re happy to announce starting with Build 15007, the same will now be possible on Mobile – thanks everyone who logged feedback requesting this! If you have a UWP app in a bad state, open Settings > System > Storage, and navigate to the app. In the advanced settings for that app, you’ll now see a “Reset” option. Tapping it will clear the app’s cache, and reset the app as if it had just been installed (without actually having to reinstall it).

Cortana loves music (Mobile): You can now use Cortana to control music playback on more of your favorite music apps (EN-US only). Starting with this build, we’ve enabled natural language compatibility for iHeartRadio and TuneIn Radio. While you are listening to music in one of these apps, you can also use your voice to control playback and volume. With radio stations, we often want to know what that catchy tune is that has played a million times, so we added support for “What’s Playing”. Try saying “Hey Cortana, What’s Playing” and it will work for all apps playing music. This appeared for Insiders on PCs with Build 14986.

Adding music recognition support to Chinese (Simplified) (Mobile): Cortana can now recognize music for customers in China. Simply tap the music notes icon in the top corner of Cortana’s home page, and Cortana will listen to whatever music is playing and use Netease to tell you what song it is. This works exactly like the feature does in English (United States). This appeared for Insiders on PCs with Build 14986.

Cortana sign-in using Azure Active Directory (AAD) identity (Mobile): This capability will allow you to sign into Cortana with your work or school account instead your MSA, enabling you to use Cortana even if your organization does not support MSA. To sign in to Cortana using your work or school account, just go to Cortana’s Notebook and “About Me” and sign in. You’ll get the full Cortana experience with most of the same features. This appeared for Insiders on PCs with Build 14986.

More recurrence options for Cortana Reminders (Mobile): We’ve heard your feedback, and we’ve added a new option to set recurring time-based Cortana Reminders for “Every Month” or “Every Year” — great for bill payment or anniversary reminders! This appeared for Insiders on PCs with Build 15002.

Web payments: Microsoft Edge now has preview support for the new Payment Request API, which allows sites to make checkout easier using the payment and shipping preferences stored in your Microsoft Wallet. This is currently in a preview state for developers and will not process payment information until a future flight. You can learn more about Payment Request on the Microsoft Edge Dev Blog. This appeared for Insiders on PCs with Build 15002.

Improved legibility for UWP apps in high contrast (Mobile): In order to address some of the most common high contrast issues experienced in UWP apps, we’ve updated the XAML framework to now display an opaque layer behind the text and coerce semi-transparent UI to be fully opaque. This appeared for Insiders on PCs with Build 15002. These adjustments are applied by default in high contrast and apply to *all* XAML Store applications, however apps will have the opportunity to opt out using the Windows 10 Creators Update SDK. More details will be available once the latest SDK has been published. If you find any issues with this work, please log them here, and as always, you can reach out to @MSFTEnable on Twitter at any time about accessibility problems and requests you have for accessibility in Windows.

Helping you find the setting you need in Settings (Mobile): One of our ongoing goals has been to make Settings easier and faster to navigate – based on feedback we’ve made a few design tweaks that appeared for Insiders on PCs with Build 15002, and are now also available on Mobile:

• Settings pages now contain additional information on the right or bottom (depending on the window size) providing links to support, feedback, and any other related settings if available.
• Since our System Settings list was getting quite long, we’ve moved app related settings out of System into a new category called Apps.

Updated device settings (Mobile): The new device settings experience combines the Bluetooth and Connected devices pages to offer a single place to manage your devices/peripherals. We’ve also listened to your feedback and added the ability to disconnect and reconnect your Bluetooth audio devices directly from this Settings page, as well as updated the flow for adding a new device connection. Try out the new page and let us know what you think through the Feedback Hub! This appeared for Insiders on PCs with Build 15002.

New option to pause updates: We’ve added an option that will enable you to pause updates on your phone for up to 35 days. To pause your phone, go to the Settings > Update & security > Phone Update and tap Advanced. This capability will be available on enterprise managed devices on Windows 10 Mobile. This appeared for Insiders on PCs with Build 15002.

Other changes, improvements, and fixes for Mobile

• In response to your feedback, alarm sounds will start at a slightly higher volume level. (They will then ramp up to full volume, as before).
• We fixed an issue Insiders with certain devices, such as the Lumia 950, may have experienced where their phone sometimes took an unexpectedly long time to show up after connecting to their PC.
• We fixed an issue where System related notification toasts (e.g. Bluetooth, USB/Autoplay, etc.) didn’t work.
• We’ve updated the experience when using Cortana to receive incoming SMS messages over Bluetooth to make it more reliable. To enable this feature if it is not already, open Cortana settings and make sure one of the following Bluetooth options is on: “Bluetooth and wired headsets” or “Bluetooth only”.
• We fixed an issue where video recorded in portrait mode might not playback with the correct aspect ratio.
• We fixed an issue on recent Insider builds resulting in the Skype Preview tile not updating with an alert badge when a new message had been received.
• We fixed an issue where certain websites pinned to Start from Microsoft Edge when tapped would perform a web search rather than opening to that page.
• We fixed an issue where the SIM Pin dialog would display truncated text in certain languages.
• We fixed an issue that could result in the phone getting stuck at the Goodbye screen when rebooting if Bluetooth was enabled.
• We fixed an issue resulting in the Outlook Calendar sometimes displaying the wrong date on its live tile after a new day has begun.
• We fixed a bug that was preventing Notification Listener apps (like wearable apps) from accessing notifications on recent builds.

Known issues for Mobile

• The Windows Hello greeting is missing from the lock screen. Showing the animation and user name is important for letting you know we have securely identified you. Of course, we also recognize the essential purpose of the Windows Hello feature is getting you to your Start screen without delay.  We’re working hard to make sign-in as quick as possible across all Windows Hello scenarios.
• AAD Identity Settings Sync: You may not see your Favorites or Reading List roam down in Microsoft Edge if you try to immediately open these tabs after opening Microsoft Edge. You can open Microsoft Edge, wait 30 seconds, and then open favorites and Reading List to see content.
• AAD Identity Settings Sync: Microsoft Edge does not sync Reading List from PC to phone unless there is a restart.
• AAD Identity Settings Sync: Microsoft Edge is syncing passwords on phone but not showing them in “saved passwords” in Microsoft Edge settings.
• When you receive a new email notification and tap on it to open the message, it doesn’t open the Mail app or message.
• New option to pause updates contains text referencing PC-only Windows Defender.
• Insiders with certain devices, such as the Lumia 635 and 636, may not be able to manually change the brightness. The brightness will still automatically adjust if it is set to do so, so please use that for the time being while we investigate.
• The ninja cat emoji display in two characters on the keyboard instead of the expected one.
• Adding a new card / paying with an existing card will not work in Microsoft Wallet.

So loads of new stuff then - some of which was highlighted by me graphically in the original post on build 14998. The big improvement for many here, including those using the AAWP Universal application, is the browser zooming fix - this means that if you've been tinkering with display scaling in Settings, perhaps to get more (or less) text on the screen generally, you won't then find that any XHTML content (e.g. from the web) gets messed up in terms of fonts.

Also notable is the first GATT support via Bluetooth, which should enable fuller notifications support for a new generation of Fitbit and other fitness related applications for Windows 10 (Mobile). More on this as apps are released.

Interestingly, Dona made no mention of the bodged update yesterday or of what to do if you installed it. I'm playing with various sequences and will report back shortly, but it looks like you're OK. Your phone should see the new update and install this on top, though the usual caveats apply - if things aren't working right then it's time for a backup/reset/restore sequence and gain yourself a fresh start.

I'll have more on 15007 later when my devices have finished restoring/updating.

Of course, in the fulness of time we'll need a summary of what's new going from Redstone to Redstone 2 (Anniversary Update to Creators Update), but we won't have a full feature set or changelog for a while yet.

Anyone with an existing phone that's officially deemed Windows 10 Mobile compatible by Microsoft can join in the fun. The full list of phones includes Lumia 430, 435, 532, 535, 540, 635 (1GB RAM version), 640, 640 XL, 730/735, 830, 930, 1520, Icon, BLU Win HD w510u, BLU Win HD LTE x150q, and the MCJ Madosma Q501. Plus, of course, all the devices which have shipped with Windows 10 Mobile in the last year, of which the Lumia 550, 650, 950, 950 XL, Acer Jade Primo and HP Elite X3 are the highest profile.

In each case:

1. Upgrade to Windows 10 Mobile (if appropriate) using the Upgrade Advisor.
2. After at least one update cycle you should then be on the Anniversary Update (a.k.a. Redstone). Head into Settings/Update & Security/Windows Insider Programme
3. Join the Insiders programme and choose the 'Fast' level in the pick list.
4. Within a few hours your phone should be seeing the build mentioned above and you'll be running next year's mobile OS today. Fun, fun, fun....!
