If you are thinking about upgrading to 1.1.1 and have the need to swap your sim card on a regular basis, do not upgrade! Unlike 1.0.2 where you just need to upload the lockdownd file to your phone and it will never ask for activation, you have to rd-activate everytime you need to insert a new sim. At this point, as far as I can tell, the only way to do this is to have activated and backed up the lockdownd file in1.0.2 for the some card you want to use. It will not work by using the current hacked lockdownd file.

Sooo... For any hacker out there that has a know how, we need a modified 1.1.1 lockdownd file so once activated and unlocked, we can swap sim cards!

Thanks!!!

In the meantime someone can tell "us" how we can retrieve the 1.0.2 original lockdownd file? Thanks

how we can backup this lockdown? i have iphone 1.0.2 unlocked by anySIM and PACAY activation

I haven't done this yet, but I suspect this is what I will have to do if no other solution comes along before I leave for the UK in early December:

1. Restore my unlocked (IPSF) iPhone from 1.1.1 to 1.0.2.
2. Activate my 1.0.2 phone using iNdependence with my T-Mobile US SIM (inputting the IMEI from my iPhone and the ICCID from my T-Mobile US SIM).
3. Backing up the lockdownd file after this activation (probably naming the backup as lockdownd.1.0.2T).
4. Pulling a copy of this lockdownd.1.0.2T file off my iPhone and on to my Mac.
5. Restoring my 1.0.2 phone again to 1.0.2.
6. Activating my 1.0.2 phone using iNdependence with my Orange UK SIM (inputting the same IMEI as before but now the ICCID from my Orange UK SIM).
7. Backing up the lockdown file after this activation (probably naming this backup as lockdownd.1.0.2U).
8. Pulling a copy of this lockdownd.1.0.2U file off my iPhone and on to my Mac.
9. Now, loading (copying) the lockdownd.1.0.2T file from my Mac on to my iPhone (so that it now has lockdownd.1.0.2T and lockdownd.1.0.2U on it).
10. Doing all the other things necessary for the upgrade, and getting to the activation process.
11. During the activation process, after backing up the 1.1.1 lockdownd file as lockdownd.1.1.1, copying my T-Mobile 1.0.2 lockdownd file (lockdownd.1.0.2T) into the appropriate spot.
12. Now doing the rest of the steps to activate (using iASign, etc.).
13. Then finally putting back in place the 1.1.1 lockdownd file (lockdownd.1.1.1).

This should leave me with an activated 1.1.1 iPhone for my T-Mobile SIM.

If I want to switch to my other SIM, I'm going to have to (I believe) get back into SSH (so I'll need to be on a wireless network), and then re-run the iASign steps after first loading up the Orange UK lockdownd file I left on my iPhone (lockdownd.1.0.2U), and then finally loading back up the lockdownd.1.1.1 file.

This should now leave me with an activated 1.1.1 iPhone for my Orange UK SIM.

The joy of the patched (i.e., factory-activated) lockdownd file that was being widely used on 1.0.2 was that it avoided the need to reactivate each SIM. If a new factory-activated lockdownd file can be put together for 1.1.1 I will be very, very happy.

If not, I'll either have to go through the prior process OR simply return myself to 1.0.2 and use the patched (i.e., factory-activated) lockdownd file that lets me hot-swap my SIMs. In truth, I'm leaning to doing the latter, although I may go through the long, involved process simply to conquer another challenge.

After thinking about this some more, I've revised my theory of what needs to be done to use a different SIM. Since some people have reported fixing their activation problems my using a lockdownd file recovered from 1.0.2 firmware (i.e., people are exchanging "virgin" copies of the 1.0.2 lockdownd file), I would suspect that the 1.0.2 lockdownd file isn't dependent on your 1.0.2 activation (provided you don't use the "factory-activated" lockdownd to bypass activation on 1.0.2). Instead, iASign reads the IMEI and the ICCID of the non-ATT SIM you plan to use and creates an activation record, which the 1.1.1 iPhone can then use once the 1.1.1 lockdownd file is restored.

I may try this later on today with my Orange UK SIM. This would make re-activating a little easier, although it would still require you to be on a wireless network when you swap SIMs (so you can SSH into your iPhone).

If it comes down to that, Mobileterminal application said to work on v 1.1.1, perhaps keep the 2 versions of the lockdown on the iphone (with a different name) and either execute a batch file that would move / rename the file names, or manually do the move / rename?

As far as I know the unlock procedure doesn't modify the lockdownd file (in fact if you want to use more than one sim, you have to install a patched one).

So it's enough save it from an unlocked 1.0.2 iPhone that doesn't have replaced it before.

Yes. Easy It's on your Mac. In your FW 1.0.2 folder. In the FW 1.0.2. DMG. Just decrypt the DMG and recover the lockdownd from the /usr/libexec/ directly.

Actually, another method for activating more than one SIM card, until such time as a new v1.1.1 lockdownd patch becomes available, is to simply backup the PLIST file from the /var/lib/Library/Lockdown/activation_records directory after running iASign for the first activation.

The v1.1.1 jailbreak/unlock instructions work fine for activating a v1.1.1 iPhone with iASign, as long as you put the "stock" v1.0.2 lockdownd in place before running iASign, and then restore the v1.1.1 version afterwards.

If you simply backup the PLIST file that's created after the first run of iASign (it should be named with your ICCID), and then run the process again for your second SIM card, you can put both PLIST files in the activation_records folder, and the iPhone will happily use either SIM card.

In fact, you can likely do this as many times as you like. The problem right now is that the current iASign process seems to remove any old PLIST files before creating a new one for the activation of the current SIM, so you simply need to backup these files before running iASign, and then put them back afterwards.

I'm currently using this method to allow me to swap between my legitimate AT&T SIM and my Rogers SIM (activated with iASign). The only difference in my case is that I legitimately activated my AT&T SIM card, rather than using iASign to do it.

The unlock doesn't modify the lockdownd, however it requires it so that you can unlock the phone. The patched lockdownd is dangerous if you plan to upgrade to 1.1.1., since you cannot activate via iAsign if your lockdownd is not the one that installed with 1.0.2. This said, if your planning to remain on 1.0.2., there's nothing like having never to activate.
