WARNING: This is not meant for amateurs. We are not responsible for any damage caused to your iPhone. Please always practice safety first.

Steps:
1. Disassemble your iPhone and remove the logic board. See Google video here.
2. Remove the EMI shield and take note of the baseband chip marked ‘X.’


3. Cover the surrounding area of the mainboard and use a hot air gun to melt the solder that holds the chip. Ideally, the temperature should be around 290 degree C. Check out some YouTube videos here.

4. Gently remove the baseband chip from the logic board.



5. Clean up any residue left on the logic board with a soldering gun and rub the area with a piece of cotton dabbed with alcohol.


6. A close-up view of the cleaned area of the logic board.


7. Now you are ready to mount the new baseband chip. See YouTube video here for recommended ways to do it.


8. Once you have mounted the chip, wait for at least half an hour before reassembling your iPhone.
9. Turn on your iPhone and check that you now have an older baseband 5.13.04.



10. Jailbreak your iPhone if you haven’t done so and unlock it with ultrasn0w. You now have an unlocked iPhone and your GPS and other issues should be resolved.  

Note: This method does not make your iPhone factory-unlocked. You still have to be careful not to update it directly via iTunes.
