Have read the FAQs but still have a few questions: My iphone was 1.1.2 OTB and have upgraded to 1.1.3 then 1.1.4. All I want to do is jailbreak it.. I do not want to unlock. Will both iliberty and pwnage allow me just to jailbreak? I think yes.. but will I still need to build IPSWs? Will this "downgrade" anything in the process? If it goes tits up and the iphone needs restoring... does itunes use a recent backup or would you loose all contacts etc? Do Apple honour warrenty claims on jailbroken phones? Does jailbreaking nuke the phones content.. or will it be left in original state? As you can see Im just a little worried about screwing it up!
