NativeCn 3.10a is out, and it’s compatible with iPhone 1.1.4. Look for it at the usual iphone.org.hk repository via the Installer App. The old version of NativeCn 3.10 is not compatible with iPhone 1.1.4.
I actually don’t recommend 1.1.4 if you are already running 1.1.3 with jailbreak and unlock with no issues. I’ve ran into a a few Installer App problems and lost of sound after the 1.1.4 update (but fixed via software full reset). 1.1.4 hackery is not entirely foolproof at this point.
