When the last iOS update came in, we said it was likely to be the last before the big step up to iOS 5. However, we hadn't reckoned on the furore surrounding location tracking on the iPhone and iPad. That's led to the release of iOS 4.3.3.If you missed it, security experts found evidence of Apple 'tracking' its users in a hidden file. Apple denied it was tracking users, but did admit it was keeping a log of Wi-Fi hotspots and mobile towers for easy access for its users. However, Apple also said there was a bug relating to the amount of data held on the phone and an inability to turn it off when 'Location Services' was turned off. This update deals with those problems.The new update reduces the size of the data file and stops the practice of backing up the cache of location data to iTunes. It also deletes the cache entirely when Location Services is turned off. Up to a year's worth of data was said to have been stored on phones, would you believe.This latest iOS update should put the matter to bed, just as long as you download it. iOS 4.3.3 should be available when you next hook up to iTunes.
