How do I know what method was used to unlock my 1.0.2 iphone?

[woodshed]

Hi All

I bought my phone from ebay about 6mths ago now. It was already unlocked and has worked great since.

I'm now thinking of upgrading from 1.0.2 to 1.1.3 (a reliable simple way of doing this is something I'm still search this and many other forums for - feel free to point me in the right direction )

One thing I've noticed searching for the best upgrade path is many 'tutorials' seem to depend on the method that was original used to unlock your phone. I've got no idea - whats the best way to find out.

TIA
Chris

I have noticed quite a few people looking for the same info I was. I am at 1.0.2 on a phone I bought in Singapore October 2007. I bought it unlocked and had no idea of what method had been used. I'm thinking of upgrading, or at least making sure I have the tools and procedures in place for when I do go ahead.

After wading my way through so many forums and search engines I managed to pull the details from several different posts.


First ensure your SIM PIN is turned off. Check in Settings > Phone > SIM PIN


From a ssh terminal session like PuTTY connect to your phone.

Stop CommCenter, type
launchctl unload -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist
and hit enter

Start minicomm, type minicom -s and hit enter

Scroll down to serial port setup and hit enter
To select Serial Device type a
Backspace over the current value (/dev/modem) and type /dev/tty.baseband and hit enter
Get out of the minicom configuration screens by hitting esc twice


Your screen should now look like

Welcome to minicom 2.2

OPTIONS:
Compiled on Jul 21 2007, 05:09:51.
Port /dev/tty.baseband

Press CTRL-A Z for help on special keys




type AT+xsimstate=1 and hit enter

The output from this command looks something like

+XSIM: 2

+XLOCK: "PN",4,0,"PU",5,0,"PP",5,0,"PC",5,0,"PS",5,0

OK

If it appears as +XLOCK: "PN",4 it was unlocked via anySIM1.0.2,iUnlock, unlock.app or hardware unlock
if it appears as +XLOCK: "PN",1 it was unlocked via anySIM1.1
if it appears as +XLOCK: "PN",5 it was unlocked with IPSF

To exit minicom press ctrl a then x
To select yes press enter
Start CommCenter again, type launchctl load -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist and hit enter
Turn on your SIM PIN again if desired in Settings > Phone > SIM PIN
