I have a Sprint iPhone 4, running 5.1, with a PPC G5 running 10.5.8. I can't find a compatible jailbreak app. I've tried redsnow, Absinthe, jailbreakme[dot]com, nothing works! Help!
Architecture Not Supported I downloaded redsn0w_mac_0.9.10b6 but when I try to open the app, it says it is not supported on this architecture. The latest Version of Absinthe (0.4) is only for A5 devices, I downloaded it, tried it, had my device plugged in and it said that my device was not supported. I went the jailbreakme[dot]com from my iphone, not supported, took me to jailbrea.kr and again took me to redsnow.
Like my boy dhlizard said. You can JB it on any computer. It doesnt have to be on the one you sync it with.
Please refrain from jacking threads. Hopefully you should get some answers in your own newly started thread.
Have you tried the newest Redsn0w Version This is 0.9.10b6! If that is the right solution for you, you can read on Redsn0w Download 0.9.10b6 or you also can try other solution like Greenpois0n, Comex, Sn0wBreeze, PwnageTool or Spirit jailbreak software. Some are older jailbreak solutions, but I have made good experiences with different iPhones.
