Apple angered some fans when its iOS 8 updated required tons of space, as much as 6.9GB depending on your device. With most iPhone and iPad owners owning 16GB models that have just 12GB available to start, the required storage meant deleting photos, apps, games or texts. Alternatively, you could have hooked up to your PC/Mac's iTunes and upgraded that way, but not everyone was in front of a computer with hours to spare.
Microsoft has made the offer available until the end of September, and it includes the OneDrive camera roll seeing a jump from 3GB to 15GB.
