launching iOS 7 generated a lot of dissatisfaction among a very large number of users, and this motivated those from Cupertino to solve various functional and design problems of the operating system. Despite the reluctance of some, iOS 7 it has already passed an adoption rate of 80% and the growth will not stop here, until the summer the operating system can reach an adoption rate of 95% or higher. Most of those who stayed at iOS 6 either they don't know about the existence of an update for their terminal, or they have an iDevice that doesn't run the new version of the operating system properly, or they simply don't want to update.
Regardless of which category you fall into, little by little you will be forced to use the new version of the operating system, and Apple Lossless Audio CODEC (ALAC), and application developers will take care of this. It is not easy to develop applications compatible with multiple versions of iOS, either iOS 7 it complicates things even more, so more and more developers choose to make their applications usable only on the new version of the operating system. As new important titles will be released and new functions will be implemented, many applications will only be able to be installed on at least iOS 7, and at that point you will have no choice and you will have to upgrade if you want to use them.
If you jailbreak things get even more complicated, because now you can quietly update to any version of iOS available in iTunes and you can jailbreak in the next second. As soon as iOS 7.1 will be launched, this option will no longer be available, because evasi0n7 it is not compatible with the future version of the operating system. Practically for a jailbreaker who uses iOS 6, in the following weeks he will have the last possibility to install iOS 7 without problems with keeping the jailbreak, after that he will be forced to stay on iOS 6 until a jailbreak solution is released for iOS 8.
To be honest, I would never go back to iOS 6 and I know for sure that many are of the same opinion.
