Discuss The ultimate iPhone unlocking reference scheme (for newbies...) at the iPhone "2G" (Rev. 1) - Hackint0sh.org; A phone with 1.0.2 firmware can be activated with a real ATT SIM tied to ...
A phone with 1.0.2 firmware can be activated with a real ATT SIM tied to a 2-year iphone contract. It can also be jailbroken (e.g. to allow 3rd party apps to be installed). Once it is jailbroken, it can also be fake activated to bypass the ATT/contract requirement.
Separate from the activation requirement, the phone comes carrier-locked to ATT. If activation is bypassed, then it can be used with any ATT SIM (or a Turbo/SuperSIM as they can pretend to be ATT SIMs for that purpose). If in addition to the above the phone is unlocked, it can then be used with any SIM. With two important caveats:
1. A phone with 4.x baseband firmware (which it has if it ever had 1.1.1) cannot be currently unlocked. If it was unlocked with IPSF before it got the 4.x firmware, it stays unlocked. There is no current way to return such a phone to 3.x.
2. A phone unlocked with the dev team method (iUnlock, AnySim, etc) will stop functioning as a phone if it ever gets 4.x baseband firmware.
As people have repeated countless times, if you have unlocked your phone and you really want to upgrade to 1.1.1, then make sure you either unlocked with IPSF, or reflash to stock firmware and then unlock with IPSF before you upgrade.
Also, @a-max, your steps are correct, but you don't need the turbosim in the phone in order to downgrade to 1.0.2. You may need to put the turbosim in there during fake activation, depending on your method. Read the TurboSIM forums...

The bottom two boxes in the far right column of the diagram are very poorly worded, and should be revised.
"...you'll be able to downgrade the firmware to version 1.0.2 and use the phone without the phone functionality..."
"...and you'll be able to use the phone functionality with an activated AT&T SIM, an turboSIM or an superSIM"
Nowhere does this path mention anything at all about unlocking the phone. So, the "without the phone functionality" box is pure fiction because I can downgrade to 1.0.2 and use the phone functionality with an activated AT&T SIM card.
Ah, but you mention the AT&T SIM card in the bottom box... where you lump it in with some turboSIM and superSIM information. What's my problem with that, you ask? How is buying a phone with 1.1.1 on it already any different than buying a 1.0.2 phone and upgrading to 1.1.1 right away (top-right box to middle-right box)? Why don't these paths converge at the 'never-unlocked and with 1.1.1 firmware' stage? Why does one path have AT&T SIM, turboSIM, and superSIM info, and the other does not?
Could it be because the info in the bottom-right box is pulled from a discussion on how to recover the phone functionality on a previously unlocked phone after being upgraded to 1.1.1, then downgraded back to 1.0.2? That discussion is completely out of place in a path starting with a newly-bought 1.1.1 iPhone. And that discussion mentioned a valid AT&T SIM card (which is kinda lame if you're talking about a diagram showing unlock options) only in the context of what's needed for IPSF to accomplish what turboSIM and superSIM can do.
In short, the diagram is convoluted and confused. I'm still trying to figure out what it's doing as a sticky thread in its present state (much less the state it was in when first made a sticky thread).

I was lucky enough to get a 1.0.2 phone for my birthday today purchased in NYC, and my parents brought it home to toronto for me. I just wanted to thank profit42 for posting the greattt guide to unlocking that worked perfectly.
Best birthday ever, got an epson 9600 printer and thanks to the guide an unlocked iPhone running on Rogers!
thanks for the guide!!
just unlocked my iphone... ran into 1 problem wit app tapp, but figured it out..
i was lucky enough to get a 7r737 yesterday...
Any tips for mac users?
The picture says that if you bought an iphone with firmware 1.1.1 already on it, you can downgrade it?
I just bought one today and it had 1.1.1 already installed on it and just wanted to know how you could downgrade a stock 1.1.1 iphone
you can downgrade a 1.1.1 but you can't unlock it as it keeps the 1.1.1 modem firmware. Downgrading only lets you use it as an ipod
here is a guide
First, download the iPhone1,1_1.0.2_1C28_Restore.ipsw from Apple. Then connect phone to dock, and hold down home button and power button for about 10 seconds until phone turns off. Now release the power button but continue holding the home button. After about 10 seconds the computer will detect the iphone in restore mode, and itunes should tell that the phone needs to be restored. Hold down SHIFT key (Windows) or ALT-key (Mac) when clicking the Restore button, and select the file you downloaded previously. Let the restore complete and ignore the error at the end. Now your phone should show a rectangle, but don't worry about it. Run AppTap to jailbreak your phone - it will fix it even though you get errors.
Does this method work for stock 1.1.1 iphones?

yes it works for fresh 1.1.1 phones out of box
Well it is my turn. (newbie)
I follow the dev team method.
upgrade to 1.0.2
Jailbreak with independence
comunity, bsd, ssh
SIM (carrier telcel) (mexico)
It worked great for a few days. Then it started saying iphone needs repair can not make or receive phone calls contact apple support.
I switched back to att sim restart, switched again, restart and worked fine for about 24 hours. Then again same message. So one day i Though it might be bugs from iunlock. So I made a restore (1.0.2) trhough itunes, same steps but install anysim 1.0.2
It worked better, stronger signal no issues. Then about 36 hours later no service.
thought all i have to do was run again anysim (still on phone) and worked again but a few hours later "no service" run again several times anysim and nothing it says it was already flashed and quits.
Trying to fix this made restore again, all process and then iunlock instead, but at the end, "no service"
Worst thing i found that since then speakers are not working not any sound on any application, video says cant be played, unless! i plugged the headphones.
I think that the theory that apple says unlocking the iphone might damage your iphone migth be true!
Does any one knows what else can be done?
I would really really apreciate your help and knowledge!
