How to use an iPhone 3GS without SIM Card and install applications not supported by iOS 6

In this Post you will make a “Untether Jailbreak” to use the iPhone 3GS without a SIM card, and will also see how to install applications made for iOS7 or iOS8 in older versions.



In my passage through the U.S., a friend was going to throw away an iPhone 3GS. I'm no fan of Apple, but I took the old iPhone thinking to use it exclusively for listening to Internet radio stations. Actually I had already done this with an old Samsung (Android 2) connected to a good speaker and the result was spectacular, even today most radios work seamlessly over the Web. To focus my favorite radios, I usually use an App called “Tunein Radio“.


The first problem was that, as the iPhone had been reset, I couldn't even access the Home (the area with icons), as always stopped on the screen with the message “In the SIM card installed”. Trying to activate through iTunes displays the message “There is no SIM card installed on the iPhone you are trying to activate”. From what I understand, by default the iPhone can only be activated with a Chip (Sim Card). But buy a chip just to use the Wi-fi phone to listen to the radio? No way! I solved it doing a “Jailbreak“.

The other problem was that the application of radio (TuneIn) and other similar applications do not run on iOS version 6.1.6, What is the maximum supported by the iPhone 3GS. The message was something like “This application requires iOS 7.0 or later. You must update to iOS 7.0 in order to download and use this application”. What to do?



Done some research on Google, trying this and that, I've reached a certain “cake recipe”. With that I was able to use the iPhone 3GS without a SIM Card, as well as install it applications made for superior versions to iOS 6.1.6, IE, IOS 7 and iOS 8. Anyway, I'm not going to explain why each thing, But how do. Is a sequence of steps not well prepared, But if you want to try your luck, There goes:

1. Write down your iPhone settings

This is optional and serves only as a precaution, If something does not come out as expected and you have a starting point to resolve the impasse.
– Look for the information in “Settings > General > About”
– Identify the model of the iPhone:
– IPhone 3GS model number is on the back cover: A1325 and A1303
– Example of information to be obtained:

       iPhone 3GS version 6.1.6 (10B500)
       Serial number 81050WZBESG model mc640HL/The firmware 05.16.08

Raining in the wet, iTunes is the software that you install on your computer to manage the iPhone.

9. Install applications not supported by iOS 6

I tried several ways to upgrade on iOS 6 the iPhone 3GS, but I couldn't (If you know, Let there!). Since iOS does not go up, so the Apps came down :)

* On iTunes:
– Go to Store > Home
– In search bar, Enter the name of the App
– Select the menu “Apps for iPhone” (to the right)
– Click the App sought/desired
– Click on the button “Get/Get” (wait for the download – Blue progress bar)

* On the iPhone:
– Open the App Store
– Click on the button “Updates” (bottom bar, to the right)
– Click “Purchased”
– The chosen App should appear “Installing”, but WILL LOCK (incomplete)
– In The Home (iPhone desktop), the icon of the App has incomplete progress bar
– Press the icon of the App (few seconds) and click the “x” to delete
– Press the Home button
– Go back into the App Store again. Next to the App there is an icon to download (down arrow)
– “Download an older version of this app?”, Click Download.
“The current version requires iOS 7.1 or later, but you can download the last version compatitible”

  1. The whole process of Jailbreak, in this tutorial, has the exclusive purpose of use without SIMcard. Having started the operating system of the iPhone (either using normally, with a SIMcard, or doing the Jailbreak) step-by-step instructions for use applications “not supported” is the same.

    This is, to install applications “not supported” (emphasis on quotes) just accept the last compatible version (why the emphasis on quotes).

    The case is that, now 2017, most of them are asking for iOS 8. And the “last compatible version” no longer available, as is the case of WhatsApp and Instagram. How does now?
