Welp, time for this tortoise to get somewhat current. My recent research has gotten me thus far, and now I apparently have a decision to make as to which app to create my custom IPSW. I see way more mentions of redsn0w, but I have used PwnageTool in the past, and like the options to include Cydia apps in the image and it also seems to have more options like "Activate" etc. At this point does it matter which app I use? To make sure I have it correct: redsn0w will "stitch" my saved 5.0.1 blob in to the IPSW file so I can do a simple Opt-restore in iTunes, but if I use PwnageTool, I will have to enter DFU mode to do that restore? But the end result is the same? I have been reading about issues (mobilesubstrate, etc.) some people had with redsn0w as recently as January; have those issues been solved? TIA!
