If you have the 4.6 Bootloader then you must follow the downgrade firmware part of this tutorial and then perform the 1.1.2, 1.1.3 OTB unlock:

How to Downgrade Your 1.1.3 iPhone (Windows)

Phone will return to activation screen, but don't panic, just wait. iPhone should automaticly restart after almost a minute. When the phone starts again, it should no longer say Slide to emergency, but rather Slide to Unlock. This means it was successfull!
How to Downgrade Your 1.1.3 iPhone (Windows)

I've had a few reports of the emergency slider not changing to the unlock slider. The best suggestion so far has been to keep the iPhone connected to the computer and make sure its detected in iTunes. Otherwise it seems to work if you retry installing AppSnapp till it works. Don't know what the issue is exactly (maybe a server load issue) but if it doesn't work immediately then try again.

DOWNGRADE THE BASEBAND
At this point if you have a 4.6 Bootloader iPhone you cannot continue any further. You can stay at 1.1.1 or you can install OktoPrep and update to 1.1.2 then 1.1.3.

I downloaded to Firmware 1.1.1 using iTunes 7.6. When I run iBrickr 0.91 I get the green screen (no reboot). What can I do to get the phone out of recovery mode?

rurock - February 9, 2008 at 12:43pm
interesting. Didn't know there was a difference. thx
iClarified
iClarified - February 9, 2008 at 12:34pm
Generally you will get Error (1) if you just attempted a restore without rebooting the iPhone into recovery mode first. Did you reboot into recovery(DFU) mode
rurock
rurock - February 9, 2008 at 12:24pm
I got the same error. there are two methods to get out of it. use iBrckr and select download to 1.0.2. It will kick the phone into recovery mode and then you can do the usual Shift-Restore to select the 1.1.1 restore file. the other method is to use iPhuc as ocumented http://www.hackint0sh.org/forum/showpost.php?p=201215&postcount=26. iBrckr worked for me.
