I have been asked several times in the past few months about iPhone 3G stuck in emergency call screen. Most of them were people who accidentally updated iPhone 3G with firmware 3.1.3 and it upgraded the baseband to 05.12.01 which still has no unlock. So here is a quick walk through which can help you get your iPhone 3G out of emergency call screen and you can than use it as an iPod Touch.
[ Quick Note ]
For those of you having trouble with Jailbreak, please make sure you are using iPhone1,2_3.1.2_7D11_Restore.ipsw file. For some reason some of the Tech sites are sending out wrong versions of this file. Please download the correct file name and match the file name before you continue.

Here is a step by step guide on How to get your iPhone 3G out of Emergency Call screen.
Step 1:
Download Redsn0w 0.9.4 and you need iPhone1,2_3.1.2_7D11_Restore.ipsw, if you notice its 3.1.2 and that’s what you need, not 3.1.3 so don’t confuse on that.
- Download redsn0w 0.9.4 for Windows
- Download redsn0w 0.9.4 for Mac
- Download Firmware 3.1.2
Step 2:
Turn your iPhone 3G off and connect it with your System with the USB Cable.
Step 3:
Extract the content of Redsn0w 0.9.4 you just downloaded and look for redsn0w.exe [Windows 7 users should right click and make the file run as Administrator]

Step 4:
Browse to iPhone1,2_3.1.2_7D11_Restore.ipsw you downloaded in Step 1. Redsn0w 0.9.4 will process it and wait for “IPSW Successfully identified” message.

Step 5:
Now click next and Redsn0w 0.9.4 will ask you to hold Power and Home button, these are easy steps, follow them and let Redsn0w 0.9.4 do the magic for you. You will notice some processing on your iPhone screen as well. Once you’re done on your computer click finish, iPhone will continue the processing and after a reboot it will start installing the required stuff and you’ll be done in a few seconds. Also, just click on Cydia when asked on one of the screens.
This is it, let your iPhone reboot and you’ll be out of Emergency Call Screen. First thing you want to do is download Fuzzyband from Cydia and check your Bootloader if you are lucky enough to be on the 5.08 Bootloader, you’ll be able to unlock your iPhone 3G with ultrasn0w.
