If you are one of those who are still running iOS 6 or run a beta version of iOS 7.1, well the maintainer of the biggest repo of Cydia he has a message for you. According to information obtained from various sources, BigBoss says that Apple Lossless Audio CODEC (ALAC), is preparing the release of an update for its iPhone, iPad and iPod Touches, most likely iOS 7.0.5, and all those who are interested in using it evasi0n7 still have to install iOS 7.0.4 in the near future, before that Apple Lossless Audio CODEC (ALAC), to block the process of signing SHSHs.
Now that iOS7 has been jailbroken, it is advised that anyone who ever wants to be on iOS 7.0.4 *ever* gets there very soon. Speculation is that Apple will release an update soon and when that happens, they will stop signing 7.0.4. Users will have a limited time window to get onto iOS7 and be jailbreakable. Further, reports are that evasi0n only runs on a freshly restored 7.0.4 rather than one a device that got to 7.0.4 via "software update". So if you haven't done so yet, now is the time to backup your device in iTunes, restore it to a fresh 7.0.4, and keep it on ios7.0.4. For those who have jailbroken, keep in mind that some tweaks may not work. And every tweak needs to be recompiled to work on ARM64 (iphone 5s) so many things installed may simply not show up until updated.
The problem is very delicate because evasi0n7 jailbreak it only works on terminals that have been restored to iOS 7.x, so an OTA Update will only bring a boot loop and not a jailbreak. As soon as iOS 7.0.5 will be released, Apple will block the ability to sign SHSHs and you will no longer be able to do so jailbreak if you do not have a suitable version of iOS installed. About iOS 7.1 beta is pointless to talk about, because there Apple will definitely block the jailbreak and you shouldn't rely on it.
In conclusion, enjoy jailbreak while you still can, because soon you will have to ignore iOS updates to be able to keep it.
