I have the following problem: my wife accidentally upgraded her iphone through iTunes to 1.13 (bootloader 4.6). I followed the guide do downgrade the baseband, and successfully did so to 04.02.13_G.
Then I downgraded to 1.1.1 (twice, actually several times by now as I retried this a few times hoping I had missed something) and jailbroke it.
Then I upgraded to 1.1.2 and again jailbroke, but I get "No Service". I tried to install iClarified method to unlock the phone but after a while it crashes the phone reboots andů nothing, I still get "no service".
I installed bosstool and have 128Mb free on system partition. I have bsd installed too, and even run the "signal fix" from sendowski, which installs fine but does not do anything.
I seem to be stuck on the iclarified step, I can't get it to install, any clues?
Which "baseband downgrade" guide did you follow? You mean the Geohot 4.6 unlock, or some other guide? I think the other guides are for 3.9 bootloader...
I used geohot's 1.1.2 software unlock guide which was published here a few days ago.
... 3. Kill CommCenter and run "gunlock secpack ICE04.02.13_G.fls"...
And yes, I enabled commcenter again.
I'm kindda confused with all this guides.
The iClarified guide states that you need to jailbreak your phone and then do everything from Installer.
This is wierd... if that's correct, why do I have to install the terminal and run that load of commands? What's the difference?
The iClarified method lets Installer run those commands. So you don't need the terminal to type them yourself. Fast and clean.

You could give the method with the command line a try: http://www.hackthatphone.com/112/iph..._112_46bl.html

Jim: I am also having this issue. I followed the link and ran the steps. When I inserted my Airtel SIM (India), I FINALLY had service. I tested it by making a call and sending an SMS.
