My co-worker wants me to jailbreak his iPhone. (only jailbreak, he is on AT&T) Is there any reason not to use Ziphone or iliberty to do this? I have used both of these programs to unlock iphones in the past, and I am aware of the bootloader issue, but I will not be unlocking his, only jailbreak, so that is not a problem. I am more comfortable with these programs that I would be with the pwnage tool, so I would like to use one of these if there is no reason not to. (probably ziphone, because I liked it better than iliberty+) Thanks for your help!
