For those users that are planning to Jailbreak on OS 3.1.3, then I recommend adding this Cydia Source into Cydia after you jailbreak so you don't have to manually input all the Cydia Sources manually. This will automatically add all the best Cydia Sources and give you access to all the best Cydia Tweaks, Themes and Apps for FREE with just a push of a button. Follow the steps below. 1. Open Cydia 2. Tap Sources 3. Tap Edit 4. Tap Add 5. Type this url in the box (cydiasource,n e t) without the spaces and switch coma for a dot in the url. 6. Tap "Add Source" 7. Install the package labelled "All Sources". This will give you all the best Cydia Sources to have access to all the best Tweaks, Apps and Themes for FREE.

try this one, I have unlocked my phone on very fast (about 6 hours total) and cheap, now i can update to any version without having to worry that my phone will be locked ever again. Only 9.99$ for phone unlocks!!

The tutorial and the links iClarified giving here are NOT MACTHING! I am now stuck with a locked iPhone. Upgraded to 3.1.3 from the given link but stuck on step 4. Its \'Unrecognized IPSW\' with Redsnow 0.9.4. D*mn iClarified!

Hey Alex, I ran into the same issue on step 4. So what I did is download the iPhone1,1_3.1.2_7D11_Restore.ipsw file and used that instead and it worked. You can get it from the link below. After I used that file I continued following the steps and it worked fine. Hope it works for you too.

I solved this problem. The link given in the download list at the top is: - 3.1.3 (2G): iPhone1,1_3.1.3_7E18_Restore.ipsw When you download this, it is \"iPhone1,1_3.1.3_7E18\" But, when you come to step 4, the current IPSW is not that version. Instead, it is: iphone1, 1_3.1.2_7D11_Restore.ipsw Google that, or download from here:,1_3-1-2_7D11_Restore/343202.htm Then in step 4, choose this file, not the first one you downloaded and used to back up your phone. The rest of the steps will work just fine.

Got it... Thanks!!! I did it on 2 different iPhone2G devices, and both are working perfectly. Just make sure you use the file \"iphone1, 1_3.1.2_7D11_Restore.ipsw\" as user \"m\" earlier pointed out. Good luck!

It just doesn´t work! Redsn0w says \"unable to recognize specified IPSW\", I followed all instructions, had 3.1.2 and was trying to put 3.1.3 - the tutorial seems wrong, for my disapointment!..... didn´t do anything wrong.. any1?

Run redsn0w 0.9.4 and click on browse. Point it to the iPhone OS 3.1.2 firmware you just copied to your desktop. Make sure your iPhone or iPod Touch is already updated to OS 3.1.3

Total confutation....what is the tutorial is going for... U put there to download 3.1.3 7E18 but U select 3.1.2 7D11 (also in windows tutorial) but U download is not the firmware. The other thing is not going for DFU mode. Is it down grade to 3.1.2 or just unlock. Pleas clear this.
