Cancel Jailbreak midway

[JasonReid]

Ok, so I started to jailbreak my iPhone, downgrading from 1.1.3 etc. I got to 1.1.2 and when I open jailbreak.jar I get an error saying I needed to install Oktoprep when I already did that. Thats where I am stuck. Unless there is something I am missing, I would like to just go back to 1.1.3 but in iTunes, it says "this SIM card is not supported" and I can't perform an upgrade or anything. What should I do?

Put the iphone in recovery mode
Restore to 1.1.1
Run Oktoprep
Upgrade to 1.1.2
Upgrade to 1.1.3

You may have to run anysim unlock sometime between 1.1.1 and 1.1.2. I don't seem to need to, once I have upgraded back to 1.1.2 the sim unlock automatically starts working again.

I have found the iclarified tutorials to be the best.
