The iPhone Dev-Team have finally released their long awaited iPhone 3G software unlock solution, called yellowsn0w. It still in a beta stage at the moment, at version 0.9.1. It works, but its not very stable.
The Dev-Team have previously warned us not to update to version 2.2 with iTunes so that we don’t update the baseband version (the chip responsible for handling sim cards) to version 2.28.00. But now, they are saying that the unlock only works right now on 2.28.00, so everyone that updated accidentally (like me), or didn’t know, your in luck! And for everyone else, this won’t work on older basebands, so you have to update your iPhone to the latest version be able to unlock it. If you updated it to 2.2 with PwnageTool (without updating the baseband), then you will have to restore your phone using iTunes.
Installing yellowsn0w is very easy, all you need is a jailbroken phone, and there are plenty of tutorials on the internet telling you how to do that. After you jailbreak your phone, go to cydia, and add the Dev-Team’s source*. After refreshing your sources, go to the changes section, and you will find yellowsn0w there. Install it, then go back to Cydia’s main menu, and reboot your phone with your sim card in (without any proxy sims like TurboSim, YesSim, etc.). After the phone boots up, it gets a bit tricky.
As far as I know, all sim cards in Egypt have something called a SIM Toolkit. This STK is the menu on your phone that gives you options that are carrier related, like paying your bill, or “recharge”, or other services. The current version of yellowsn0w is a bit buggy with sim cards that have the STK. To get around that, after the phone boots up, and goes to the homescreen, you have to wait 60 seconds, then take your sim card out, and put it back in. If it works on its own, then great! You’ll have to do this every time you reboot your iPhone, at least until the Dev-Team comes up with a solution for it.
There is a lot more info on the Dev-Team’s blog post, which is you can find here. Please read it carefully before proceeding with the unlock, and make sure that you do everything correctly.
This procedure should not brick your phone in any way, and is easily removable using Cydia. But I will not be held responsible for anything that goes wrong with your iPhone. But I will of course be glad to help anyone who has any problems.
* You will find the Installer and Cydia sources in the link above, I am not allowed to link to it directly.

Hi tawakol,
Actually i did several times even by removing yellosn0w and restoring to factory settings through itunes then jailbreaking again and then installing yellowsn0w with local sim inserted and fails again!! i kmnow it is weired as i know many people does succesfuly.
I guess as i do not have the original sim inserted so i cannot change/update the base band.
This is all.

can you tell me what your baseband right now is? and did you try updating/restoring without the sim card inserted?
January 18th, 2009 at 8:00 pm
hi twakol,
My baseband is the one recomended by Dev team but, what is i might did not do is the update without the sim card inserted which i can do right now.

Dear Egypt Apple community Group Admin.
I need your urgent advice please
I connected my IPHONE to the It tunes, and it said my current software version is 2.2 and there is a new version available 3.xxx I cannot recall it exactly.
I strarted the upgrade process, I reached to the final step which is to disconnect the IPhone and to insert the Sim Card and to connect again to the Iphone.
I followed this step, but it turned to be that The Iphone now does not recognize the sim card {mine is vodaphone open invoice Business subscription)
I assume that this new software version have locked the mobile for AT&T Sim card only, {only assumption}
So need to know what to do to unlock it, and to return it back to the origional status, and if there is any possible way to upgrade to a newer software without facing this problem again?
What to do, and how to do- appreciate your help as I am turned off without the mobile, and all contacts, and calender, and all appointments are on this device, so really appreciate your urgent help and advice. I beleive mine is 2G not 3G
Regards

go to http://www.blackra1n.com
download the program on that website
run it, and press the button while the phone is connected
wait till it finishes and the phone restarts
you will find an icon called “Blackra1n” open it
install cydia AND the unlock
thats it!

@Ahmed Gamal
My friend you will find everything here. http://www.iClarified.com/entry/comments.php?enid=5886#commentsanchor
There are screen shots and videos to drive you as well.
You must jailbreak first your iphone with blackra1n and after you will find in the Cydia un application with name blacksnow. You will runthisapp and your device will be unlocked again.
(Cydia is something like appstore with very interesting apps but not approved from apple)

@fast916
