I'm a bit surprised at how slow some of the major tweak devs are at responding to iOS 9. There are several show stoppers preventing me from upgrading from 8.4 and I'm likely to miss the signing window for 9.0.2 at this rate.
Careful, you'll get crucified for saying that. You're supposed to wait for updates, but of course when the updates come 2 more Apple updates have come one gone. Personally I'm surprised the updates aren't sooner, couldn't the devs work off of the betas which were issued months ago? Maybe it's different for JB apps versus vanilla apps in the way the devs need to approach them.
Honestly I'm not seeing much to keep me JB, not very much works on my 6s+, but then again there isn't much in 9.1 that is enticing so I can be a bit patient. I was hoping for Eclipse, but I can't use the beta because I didn't buy eclipse 2, and I can't purchase eclipse 2 because Cydia won't let me, sigh. I think I'd be happy with Eclipse or something to give me a system wide dark theme, and infiniDock.
