EDIT (17:54GMT): this is an unofficial fix and Saurik recommends against using these unofficial fixes (see THIS). On my 7.0.4 iPhone 5, I haven't encountered any problems after a day's use, frequently (manually) rebooting etc. However, your mileage may vary. I'm personally sticking with it - again, I haven't encountered any problems and it greatly helps after reboots. For example, with it, I don't need to do a three-step MS reinstall + recorder reinstall + respring sequence with my call recorder after every single reboot (see THIS). Original post: 1, add the source parrotgeek.net/repo. Note that it'll display some warnings during discovery (see screenshot below)); it's nothing serious, just some missing user data from the control files: 2. get "Mobile Substrate fix" from the repo: So far, on my iPhone 5, I've found it working great with: - FakeCarrier - my Call Recorder Absolutely no need to reinstall MS after reboots.
