Apple has your unlocked iPhone in their crosshairs. What do you do? Here's my first go at a re-locking guide. I'll update and confirm as time and feedback permit. This method in no way guarantees that your iPhone will survive the update after being unlocked.

If possible, deactivate your iPhone. Use whatever method you used to activate it if your iPhone is not activated with AT&T.
Download the 1.0.2 firmware to your computer and unzip it. It uses a .ipsw extension but your unzip program should still work. Change the extension if you have to.
Extract the ramdisk as such: dd if=009-7698-4.dmg of=ramdisk.dmg bs=512 skip=4 conv=sync
Mount the extracted ramdisk.
From the ramdisk, copy /usr/local/bin/bbupdater, /usr/local/standalone/firmware/ICE03.14.08_G.eep, and /usr/local/standalone/firmware/ICE03.14.08_G.fls to your iPhone. Place these into a folder on the OS partition (such as /bbupdate) and not into a folder on /var/root. The /var/root partition is set noexec and you cannot run programs from there.
Disable com.apple.CommCenter.plist--either using UIctl or launchctl: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
On the iPhone, navigate to the folder where you stored bbupdater and the eep and fls files.
Run bbupdater as such: ./bbupdater -f *.fls -e *.eep
Reload comm center: launchctl load /System/Library/LaunchDaemons/com.apple.CommCenter.plist
