People have been asking a lot about the Gevey SIM and if it supports the country they are in. I contacted the support of Gevey SIM and did not get a reply. They are probably busy managing the huge orders. Anyways, I have compiled a list of countries that support the 112 emergency number. Remember, if your country supports the 112 number, only and only then you can unlock iPhone 4. If you country is not in the list don’t bother ordering it and wait for the software unlock for iPhone 4.

Warning: We at TechSliver still do not support Gevey SIM due to its current legal status in some countries. This is just an information we are sharing.

Now, of course I have no way to test if Gevey SIM works in all the countries above. But if your country is not listed here or if it “is” listed and 112 doesn’t work do let us know and we’ll update this. I hope this clears all your questions and now it would be easy for you to decide. Also, some countries redirect 112 to some other local emergency numbers. But I think Gevey SIM just needs a ringer on the other hand, so if its dialing Gevey SIM should work.

You can read more about Gevey SIM and how it all started to know it better. Here is a complete guide on how to unlock iPhone 4 using Gevey SIM.

Warning: This is not a final list, or not an official list. Its not necessary that Gevey SIM would work in your country, this is a list of countries that support 112. Also, most of these countries redirect 112 to a local emergency number. So check with Gevey SIM official site before buying or rushing into any purchase.


For those of you who might know, Gevey SIM has the ability to unlock an iPhone 4 on baseband 2.10.04 or 3.10.01 running iOS 4. This was confirmed when users themselves tried it and so there are no rumors about it whatsoever.


Gevey SIM supports:


iOS:

• 4.2.1
• 4.1
• 4.0.1
• 4.0

Basebands:

• 3.10.01
• 2.10.04
• 1.59.00

The phone will be locked again, if the phone’s battery runs out or it is restarted in some case. It is just like a tethered jailbreak, you have to carry out the process once again. Look at the following steps to unlock iPhone 4 on 2.10.04 / 3.10.01 using Gevey SIM.

Warning: The process is not recommended by TechSliver due to its current legal status so proceed at your own risk.
How to Unlock iPhone 4, Baseband 2.10.04 / 3.10.01 Procedure!

[ Step 1 ] Turn off your iPhone 4 and insert both Gevey SIM and your own SIM card using metal SIM tray.

[ Step 2 ] Turn your iPhone 4 back on and you will see a SIM Welcome menu, simply select “accept”.

[ Step 3 ] At the beginning you will be able to see a “no service” message on your iPhone. Now you have to wait for some time to see the signal bar.

[ Step 4 ] Once the signal bar appears on the top left corner, dial “112″ and hang-up within 2 seconds.

[ Step 5 ] Turn your Airplane Mode on and then turn off right away. You will now see a “SIM Failure” message on your iPhone and then you will see “No SIM Card Installed”.

[ Step 6 ] Turn your Airplane mode on once again and turn it off right away again until you see the “No SIM Card Installed” message showing up. You will now see a ‘SIM Failure’ message and after few seconds the signal will show up.

[ Step 7 ] The process is complete and now you have your iPhone 4 unlocked on baseband 02.10.04, 03.10.01 using Gevey SIM.

However, the process is a bit temporary since if no signals appear, you have switch off your iPhone and follow the steps all over again. The process is for the people who are really tired of waiting for software unlock of iPhone 4 and cannot wait any more.

It is something that is mentioned a lot on iDB throughout our jailbreaking tutorials and other jailbreak-related news. “Make sure you save your SHSH Blobs before you update,” is a pretty common saying around these parts. We’ve been asked several times lately what it is, so I figured I’d post it.
An SHSH Blob is basically what Apple uses to verify the version of iOS you are running. That’s why we tell you to save your SHSH Blobs before upgrading your firmware on your iDevice. Otherwise you might not be able to downgrade to a previous version in the event you needed to.

That is unless you managed to save your SHSH Blobs with a program like TinyUmbrella. Doing so will allow you to trick iTunes, into thinking you are running an older version.

“Cody, why can’t these SHSH Blobs just be downloaded like everything else?”  Your SHSH Blob is device specific. It uses the ECID (Exclusive Chip ID) of your device, along with a challenge key, as part of the authentication process with Apple.

Because that key is static (doesn’t change), and you’re using the same ECID, it is possible for you to save your own SHSH blob for later use. It can then be used to downgrade your iDevice if you accidentally update your firmware and there’s no jailbreak available.

Now make sure you save you SHSH blobs. If you don’t know how, this tutorial will show you how to.
So is anyone as confused as I am? Just kidding. I tried to keep it pretty simple. Does anyone have anything to add or have questions? Sound off below!

With the release of Spirit now imminent, it would be a good thing to save your SHSH blob, in case you need to downgrade in the future. Saving your iPhone SHSH is very simple.
Step 1: Download Firmware Umbrella from here.
Step 2: Launch Firmware Umbrella and plug your iPhone in.
Step 3: Click “Save My SHSH” and wait for Firmware Umbrella to do the job.
Done! A copy will be saved to your computer and it will also send a request to Cydia to save your SHSH on Saurik’s server.

TinyUmbrella Updated Again, Adds iOS 4.3 and iPad 2 Support



In addition to iOS 4.3 support, the updated TinyUmbrella (version 4.30.00) also brings iPad 2 support for all models (WiFi, CDMA, and GSM), and a new tweak requested by the creator of Cydia, @Saurik. Notcom also mentions that users who do not update to the latest version of TinyUmbrella, may experience significant slowness when saving their SHSH blobs in the future…

TinyUmbrella now supports all three new models of iPad 2. I’ve also added a much-needed tweak per saurik’s request. If you don’t update to the latest version, you may experience /significant/ slowness when saving your SHSHs in the future. With this release, 4.3 is supported. I plan on making some changes to the UI to help out the poor saps stuck on vertical resolutions < 900. I’m also going to be removing the proxy section of the app and simply using the system proxy settings.

As a reminder, to save your SHSH blobs, simply connect your iDevice via USB to your computer, launch TinyUmbrella, and click the “Save SHSH” button.
