From the blog post:
Tonight, we are pleased to announce that we are doubling the amount of free storage you get with OneDrive. While it might seem strange to announce new features on a Friday evening, we’ve been listening to the commentary about storage on the new iPhones released today and we wanted to get you more storage right away. We think you’ll appreciate having more free storage while setting up your iPhone 6 or upgrading to iOS 8. It’s a limited time offer, so act fast and download OneDrive for iOS.
All you have to do is sign up for OneDrive and activate the auto upload feature for your camera roll sometime between now and the end of September, and you will get 30 GB of free OneDrive storage moving forward (15 GB base and 15 GB camera roll bonus). For those getting ready to install iOS8, this means you won’t have to delete a bunch of photos or apps to make room for the upgrade. For those buying a new phone, it means you can take all the high resolution photos and videos you want without worrying about the amount of storage you have.
Not an iPhone user? Don’t worry, we’ve got you covered. This also applies to anyone who already uses the OneDrive camera roll on Windows Phone (Windows Phone Store), Android (Google Play Store) and Windows (Download) – you’ll see your storage go up as well. Same for any existing iPhone users who backup their photos to OneDrive.
I can confirm that this has automatically been applied to Windows Phone users with auto-backup turned on. Going into my OneDrive application on my Lumias, I now see:
This is all from 'Settings' in the OneDrive application. The 'Camera roll bonus' was previously about 3GB, I think, so the increase today for us all ends up as 'only' 12GB, but it's still a very welcome increase.
Note from the screenshot above right that the 'enthusiast' bonus, news posted Christmas 2013, is about to run out for us all, so make sure you have at least 20GB free before this amount gets subtracted at the end of the year, otherwise you risk new uploads being disallowed, etc.
Comments? Are you living happily with free storage or have you paid up? Or maybe you got the extra 1TB(!) that comes with Office 365?
