iPhone 7 jailbreak taking too long?
You missing a piece of the context, your quote is from pimskeks, it's a reaction to @pod2g's ttweet:
'pod2g @pod2g 4 october
Again, and like usual, we can't give a release date for the iOS 7 jailbreak. We can run into different troubles
No idea.'
The timing pimskes refers to is the different releases, a 7.0.x or later might close the exploits.
This does not mean they are waiting for 7.1
There is always a trade off between burning exploits and how many people you can reach with a JB.
The 5c/5s/ipad air and mini retina are out, 7.04 is stable, no use not to release if the JB is ready.
A 7.2 can happen so can a 7.05.
You are jumping to conclusions on multiple points.
For now it just isn't ready, just wait it out, they will release when ready.
