@ALL. I just finally did it and IT DOES WORK PERFECTLY!!!
I used iClarified.com method on this thread

FOR YOUR INFO:
I was on 1.1.2 with bootloader 4.6 out of the box. I was using x-sim and decided to give it a go.
Took the x-sim out of the phone and then followed the tutorial.
Before I made sure I had enough space.
Note the spinning wheel seemed to get stuck, then without the notice, the phone rebooted on its own.
Then it connected directly back to Vodafone Spain.

Thank you!!

PS. Please confirm someone if after this, softupgrade to 1.1.3 works and which method is best?

i did run Geohot unlock with my T-mobile (US) sim in the phone. i get a message say that my iphone had been unlock however i can't make calls. First time i try with the original AT&T and there was a circle frozen on the screen and it reboot and after that i insert my Tmobile sim , it does show the t-mobile signal but can't make call, i did install iWorld for United States but still i wasn't able to make calls. does anyone have a solution for this? i really need help!

I've tried this a couple times with my 1.1.3 OTB and I keep getting an error message only instead of 1015 it's 1, then the rest of the steps don't work, any suggestions, I really want to play with my new phone, lol.

I got as far as opening windows.bat, and then hitting "jailbreak" (while on 1.1.2). It then tells me:
Jailbreak Failed
An unrecoverable error was encountered during the jailbreak. See console for details.

Any help?

I did it! I mean, geohotz did it and i followed his path.
I installed iWorld, selected Brazil [which is where I actually am], and everything is working perfectly, calls and sms.
super easy, even for a girl. (;

ANYONE: Please confirm if after this 1.1.2 unlock , softupgrade to 1.1.3 works and which method is best????

Hey you make me confused...

This is the Geohot method (IPSF-like, restore resistant) for BL4.6 1.1.2 or 1.1.3 OTB phones! Works with 16GB too!!!

Is it true that this Geohotz's gunlock method = IPSF-like method?????
If it is, it should mean that when I unlock my iPhone with gunlock then my iPhone is unlocked, then I "upgrade through iTune" for 1.1.3 FW + 4.03.13 BB, and my iPhone has to be still in unlocked state with new functions in 4.03.13 BB????

Is it true?????

I don't think so...
Coz I saw gunlock.c and I saw George open the 4.02.13 fls file to patch it for unlock before "write like hell" to iPhone. So it looks like to me that if we unlock the iPhone with gunlock method and happen to update again using iTune for 1.1.3 FW + 4.03.13 BB, the new (unpatched!!!!!) BB should overwrite the unlocked BB 4.02.13 in our already unlocked iPhone. And so, this is not IFSF-like method to me...

My $0.02; please help me clarify this...

I got a quick question guys. It say you need BSD subsystems. Is it ok to have the original bsd subsystem instead of 2.0 or do you need to update bsd subsystems first?

1.1.2 oob 4.6 downgraded to 1.1.1 bsd installed (basically, all requirements are met) -im in the u.s.

inserted t-mo sim, install completed- not working

uninstalled unlock, removed sim, reinstall unlock, insert t-mo sim- still not working

even tried restarting phone. also tried installing from modmyifone
sometimes i get a "no service" sometimes just dashes (searching for signal?)
but all in all, not working. call fails every time.
however, i do get a notification that i have a voicemail, but every attempt to call (voicemail or not) fails

im so close it hurts. so any help would be awesome, so awesome i might wet myself. thanks.
