When does the next iPhone update come out?

I want to jailbreak my iPhone again it's the 4s I updated it by accident and want to downgrade it I tried restoring it with the 6.1.2 ispw on iTunes but it won't work and don't know how long to wait to be able to either jailbreak or how to downgrade it on my Mac so I can jailbreak it please help

Well iOS7 only came out not long ago so another 6 months id say

Well there's a way to jailbreak but it will be a semi tethered jailbreak witch means you can use it but any cydia apps won't work along with safari won't open only crash till you reboot via redsn0w but the update would be in a few months they are working on a untethered jailbreak so i say wait a few months gor that then it will be nothing
