I have a 3GS and would like to jailbreak it so I can install Cydia etc. I searched this forum and found blackra1n is the most easy way but youtube won't work. There should be a fix by installing "push fix" from http://cydia.iphoneil.net/ but the file is no longer availble. So I am thinking of using PwnageTool but it needs to create a customer install IPSW. Would it a good move? P.S. I don't need to unlock my phone i.e. I will stick with my "Apple offcial carrier". Thanks.
