I have a very stable JB with Chimera currently, but I also also don't want to get stuck on an OS that will eventually not be supported by certain apps going forward. Should I update to 13.3 in anticipation of the upcoming JB release? If so are there certain steps I should follow (tweaks backup, save blobs, etc)? Or can I just save blobs and Restore to an unsigned version? Any guidance would be greatly appreciated, I feel like I'm on a ticking clock with 13.3 possibly not being signed any longer. Thanks in advance.
