Capacity of iPhone and hidden space or programs?
My 8GB iPhone 3GS has a total capacity of 6.2GB, as shown in settings of my iPhone. Further, a friend's 8GB iPhone 3GS shows a total capacity of 6.7GB, but after being restored to factory settings with the iTunes in my laptop, its total capacity drops to 6.2GB as well. This is not owing to new version of iOS; indeed, I gave a new 8GB iPhone 3GS to another friend last year, and the iPhone also shows a total capacity of 6.2GB despite its iOS4 (not iOS 5 or iOs 6).
Clearly, there is something wrong here. A friend suggests this is a virus that reduces iPhone's total capacity, but Apple technical team hasn't yet been able to figure out a way to clean the virus. Another friend told me rumours about *** randomly select iPhone users to monitor their usage and private activities, and the missing storage space are taken up by these hidden spy programs. For iPhone 5 and 4s users with much larger capacity, this problem cannot be identified because iOS reserves an extra space of 1GB or 2GB in all iPhones, and the spy programs, if they were really here, could hide in such reserve space.
Any expert could shed some light on this troubling issue? Thanks!
