Today, as I finally managed to finish my October Fix, I created the tutorial on fixing the No Service issue that appears when you bypass your iPhone 4. This effect is usually caused by a lack of the correct activation ticket which in term causes a lack of carrier bundles so that the phone can't recognize the SIM card.
This patch works with iPhone 4 devices (3,1) GSM only. This might not work for all carriers in the world, so don't take it a as a guaranteed solution. I try to extend the compatibility to as much carriers as possible, be patient.
This only works for devices bypassed with my tutorial.
