Hello all. I have had an iPhone since the orignial and I am just now trying to jailbreak it and I know people that have it and use greenpois0n and it works well, so I tried to download it and everytime I do, it tells me it can't run on this systems architecture. I am just wondering if anyone else has had this problem and knows what to do. Thanks anyone for the help I would really appreciate it. Oh, and I am on a powerbook g4 it is older from 2004, but I am running OS X 10.5.8 so I am not sure if that helps.
