All those iPhone users who have upgraded to Apple’s new İOS 6 software have been claiming and complaining that their mobile bills have rocketed after data usage has shot up – possibly due to a bug in how the OS switches between 3G and Wi-Fi connections. Some have used gigabytes of data in just a few days,while previously using only a small percentage of that amount when running iOS 5. Apple has not identified any specific cause for the use, though one source pointed out that with iOS 6, there are more options (than with iOS 5) to use cellular data, eg with iTunes Match, the iCloud service’s, Documents and Data synchronisation, etc. Finally, here are some tips to reduce and control your data use.
iTunes Match can be turned off in the Settings of the iPhone. Settings for synchronization of photos, documents and data can be turned off in the iCloud settings, in the Settings app.
