On the heels of Apple’s announcement that
iPhone unlocking software could cause irreparable damage to the iPhone, many people are now looking for a solution to relock them.

The folks over at Macnn have come up with a solution to relock iPhones that have been unlocked. They also state that there is no guarantee that it will work and they assume no responsibility if the relock goes wrong, but hey, if you’ve already unlocked the phone, it will be rendered useless anyhow.

To relock your iPhone follow these procedures:

* on your Mac, go to your home directory and create a directory called relock
* set your iPhone to never autolock the screen
* put a copy of the 1.0.2 firmware in a directory on your Mac. If you need to download it, get it from here.
* rename the extension on the firmware from ipsw to zip
* unzip it
* run: dd if=009-7698-4.dmg of=ramdisk.dmg bs=512 skip=4 conv=sync
* use finder to navigate to the directory where ramdisk.dmg is and double-click it to mount it.
* copy the following files to the relock directory you created in the first step:
o /Volumes/ramdisk/usr/local/bin/bbupdater
o /Volumes/ramdisk/usr/local/standalone/firmware/ICE03.14.08_G.eep
o /Volumes/ramdisk/usr/local/standalone/firmware/ICE03.14.08_G.fls
* on your iPhone, run: mkdir /relock
* copy those three files to your iPhone: scp -p bbupdater ICE* root@youriphoneip:/relock
* on your iPhone, run: cd /relock
* on your iPhone, run: cp /System/Library/LaunchDaemons/com.apple.CommCenter.plist /var/root/media/com.apple.CommCenter.plist
* on your iPhone, run: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
* on your iPhone, run: ./bbupdater -f *.fls -e *.eep
* on your iPhone, run: launchctl load /System/Library/LaunchDaemons/com.apple.CommCenter.plist
* on your Mac: exit iTunes
* on your Mac: kill iTunes helper
* manually place your iPhone into recovery/restore mode
* connect your Ihone to the computer and start iTunes
* restore your iPhone
