I need advice on how to perform the semi tethered jailbreak. I know that I need the ipsw file and Redsn0w and that I would need to jailbreak it the regular way and then use SemiTether to get the semi tethered jailbreak. I am having problems with how to Boot Tethered, if I need to, without Internet using Redsn0w. And any help with the JB process for an iPhone 4 CDMA would be helpful too.
Thanks.
