I see your problem, but for us who are part of the jailbreak community there's nothing more to do than wait for the iOS 8 release (golden master). Indeed, hacker i0n1c has already jailbroken 7.1 on an iPhone 5c, iH8sn0w did it on the 4S and winocm was the first one to even show a working jailbreak for iOS 7.1 and up. BUT they don't plan on releasing public jailbreaks at all, which is kind of logical: it would be a waste to hand over those exploits to Apple so that they can fix it in a simple update or upcoming iOS 8 beta.
So what I think is that, YES there will be an iOS 7.1 jailbreak released, but don't expect it to come out before the final version of iOS 8, it is even hypothetical that there would be an iOS 8 jailbreak out before a 7.1 JB lol. The reason for that is as I said, to save exploits. But of course, if there would be an iOS 8 jailbreak prior to a 7.1 JB, it will most likely just be for those who didn't update or are out of luck of having iOS 8 on their devices and are stuck with old 7.1 (iPhone 4 probably and maybe 4S?: if only i4 then the 7.1 JB will be an untethered version of Geeksn0w, if also 4S won't get iOS 8 then there will be a new jailbreak released, as Geeksn0w doesn't support 4S).
And if the exploits they found on iOS 7.1 still exist in iOS 8, I believe the Evad3rs will simply release an iOS 8 jailbreak tool supporting both iOS 7.1-8.0.
[P.S.: for other people wondering if there is a 7.1 jailbreak, YES (semi-tethered) but ONLY for iPhone 4, google more about Geeksn0w.]
