You can no longer downgrade from iOS 7 to iOS 640
After a significant period oftesting, Apple's overhauled iOS 7 has made the move and gone publicand official. As with any major software rework, there was noshortage of bugs (some bigger than others), nor was there a lack ofcomplaints about the new look of the OS. At PhoneArena we're overallhappy with the new iteration of iOS – it sure is a work in progressand needs some tweaking, but the change was definitely needed, andfor the better.
As always, however, there are thosewho don't quite like the new OS and want to revert back to iOS 6.Whether their concerns are strictly related to the new design, orthey simply suddenly found out just how old their iPhone 4 is getting(the oldest iPhone to support the new OS), due to the significantly moreanimation-heavy iOS 7, they're simply not given a voice. Said more explicitly, in a typical Apple fashion the plughas been pulled on iOS 6 officially, meaning that whatever ways youcould find to revert back will no longer work. That's not to say youcan't revert back to it at all, it's just that Cupertino has stoppedsigning older firmware, meaning that you won't have access toessentials, such as the iTunes store.
Some of you will be quick todemonize Apple for this, and we fully get it – we're, after all,enthusiastic proponents of choice. On the other hand, Apple hastraditionally kept OS fragmentation to a minimum thanks to a strong hand approach like this -- a goodthing for a number of reason, like an overall better and moretargeted support for our iPhones.
