I just bought an iPhone and it has been unlocked by the seller. My iPhone is running firmware 1.0.2 and I want to upgrade it to fw 1.1.2 but I don't know which unlocking method has beeng used. All the guides warn me for IPSF unlocked phones.
Is there a way to retrieve the unlock method which has been used?

I found this in some other thread, I think "Aviegas" provided it:

Try running minicom and check the unlock status of the comm board. You must be careful, because if it survived the update, it can be IPSF....

Since you did replace the board and have not asked how to "bbupdate- v" here goes a quick & dirty:

Run minicom -s
Go into config, set the device to /dev/tty.baseband
exit config, not minicom

Enter the following AT command: AT+XSIMSTATE=1

Post the result line like:

+XLOCK: "PN",X1,X2,"PU",X1,X2,"PP",X1,X2,"PC",X1,X2,"P S",X 1,X2

X1 and X2 are the important data:

1,0 is locked or new anySIM unlocked - this is the "good state"
5,0 is IPSF - the paid state
4,0 is iUnlock and siblings (unlocker, and anySIM 1.0.x) - needs revirginize

edit: although the poster did not mention this but I think you have to shutdown commcenter before going into minicom and issue the AT command.

Ok, i tried this on another iPhone with FW 1.1.2 (AnySim unlocked) and it gave the following result:
So I'm unable to use this on 1.1.2 firmware models. Still have to try on my own 1.0.2. iPhone though

Tried this on my own 1.0.2. and got the same response from minicom. What am I doing wrong?

you need to shutdown commcenter first.

launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist

when done, turn it back on


launchctl load /System/Library/LaunchDaemons/com.apple.CommCenter.plist

I did that, otherwise I couldn't get into the baseband......... still I get the message above

nothing new here but another method using sendmodem

Finally! Cracked it. Phone reports:
Which means?

+XLOCK: "PN",X1,X2,"PU",X1,X2,"PP",X1,X2,"PC",X1,X2,"P S",X 1,X2

X1 and X2 are the important data:

1,0 is locked or new anySIM unlocked - this is the "good state"
5,0 is IPSF - the paid state
4,0 is iUnlock and siblings (unlocker, and anySIM 1.0.x) - needs revirginize
