So I went through all the motions, from 1.1.3 downgrading to 1.1.1, ocktoprep, 1.1.2 update, jailbreak, etc. I ran the 1.1.3 iBricker, everything went fine, it put the soft upgrade on my phone, but now my phone tells me I have an incorrect sim. On top of that (or, actually, below it) there's the connect to itunes symbol you see in recovery mode. Absolutly nothing i've tried will change this.

I've tried the jailbreak program for 1.1.2 to boot out of recovery mode, and it just sits at "sending commands". I've tried iBrickr, iPhuc, and I've tried resetting/rebooting both my computer and phone many times. I even went into the preferences (by way of the *#306# contacts trick) and tried resetting the whole phone that way. Nothing.

Should also mention that I started (yesterday morning...) with a perfectly jailbroken 1.1.2. Had it since launch. The phone's had every firmware version out on it since, and this is the first problem yet.

Someone please help!!!

You forgot to mention which OTB version your iPhone is.

What exactly is OTB? And how do I find out which I have?

OTB = Out of the box.

Sorry, thought I did. Was either 1.0.1 or 1.0.2.

Running the field test, it shows version 04.03.13_G (1.1.3 I believe)

Edit: I got it into DFU mode, and shift-restored to 1.1.1. Now i'm stuck with the same SIM Incorrect error and even going to the jailbreakme website, etc, nothing's working.
