Most tweaks and Mobile Substate aren't ready. It might only take a day or two for Saurik to get substrate updated. I'll let you know when it has been updated or you can keep an eye on @saurik and @musclenerd on Twitter yourself.
You're right. I watched a video of a known youtuber who discusses jailbreak stuff and Apple products, they jailbroke their iPod Touch in the video. It was smooth, but yeah as you said, substrate needs updated/fixed. Saurik says that Taig is in the process of updating the jailbreak kernel patch.
Windows is now setup on my Mac, so once I see all is good then I'll do what I gotta do.
I'm surprised you tried it so soon despite everyone recommending to wait until the jailbreak is more stable and for the kernel to be patched. Most things aren't working yet and it's very buggy and unstable. We don't know how long it will take to get patched, but sometimes it's just a day or so. After that, apps and tweaks will slowly get updated. I will post when it's ready.
I defenitely would not attempt it on any of my devices it right now. It's pointless. Despite all the warnings, if you still want to try it for testing purposes in its current state, you really need to be a diehard and do some reasearch as to what to expect and give you step-by-step directions. The jailbreaks we've had for the past couple years are made by the Chinese. They aren't like the old jailbreaks that were ready to go on day one. Kernal patches for Substate are required before they are ready for the public. Also, their early versions have a Chinese user interface and you won't be able to follow the directions unless you have them translated with a guide. They usually end up getting updated with an English version.
I'm excited to see this thread. Even though I'm comfortably numb with my almost perfectly stable 8.1 jailbreak it's refreshing when there are new tools and activity on the scene. I'll have to look up the new features that 8.3 has and decide if it's worth updating and jailbreaking again, but it's so nice to know I can, once a stable Mac version is released. Hats off to the Chinese crew and the rest of the jb community for working so hard to bring us these subtle pleasures.
