How To Sign Unsigned On Ur N97

There are a lot of ‘unsigned’ applications floating around the web, partly because part time developers either do not have the time or money to get their applications signed via the Symbian Signed program. While quite a bit of such applications can be signed via the Open Signed website, some cannot be and quite frankly there are times when we are simply lazy.

For all such reasons it is best to have a developer certificate with which you can sign the files on the phone itself and install without having to bother with any other method. The following tutorial will show you how to get a certificate (generally within three hours) and is much easier than the OPDA method.

HOW TO GET A CERTIFICATE AND KEY FOR YOUR S60V5 DEVICE

Simply visit http://isign.imobile.com.cn and sign up for an account.

Fill in the required details, use can even use a fake address. Just keep the user name and password in mind.

Follow the directions in the screen shot.

Now enter your IMEI number.

The website will display a confirmation.

Now the wait begins. When I tried, I got my certificate in about 3 hours time. If you are not already logged in, login to see if your certificate is ready.

If you see a screen like the following, it means your certificate is ready for download.

Thats it, now simply unzip the file and get signing. There is no need of a Sign Key pass code.

The best part was that I could do all of this lying in bed, right from my N97’s browser. The bottomline being that I got a developer certificate in less that 3 hours without needing a computer. The next step is to sign the application from the phone itself,

HOW TO SIGN UNSIGNED APPS ON YOUR S60 5th EDITION DEVICE

REQUIREMENTS:

A S60 3rd Edition or 5th Edition device.

A freeware called ‘Free Signer’ which you can download here.

INITIAL SETUP:

Transfer the .cer and the .key file to your phone.

Install the application on the phone memory or the memory card/inbuilt storage.

Open ‘Free Signer‘, select options and then Settings.

Come to the fourth option, ‘Sign Cert’ and click on it, then navigate to where you have placed the .cer file on your phone and select it.

Do the same for the .key file. You should now see a screen like the following one.

Next simply hit ‘Back’. You are now ready to sign unsigned applications on the phone itself. Please note that you will need to do the above only once.

SIGNING APPLICATIONS:

In order to sign a unsigned file present on the phone, click on ‘Add Task’ and navigate to where the application is located. Once you reach the file, hit ‘Options’ and select ‘Add’.

You will then be presented with the following screen, simply select ‘Sign Sis’ from the options.

The file will show up, waiting to be signed. To sign it, simply hit ‘Options’ and then ‘Go!’.

That’s it, your unsigned application will now be signed without you needing to use a computer. You will be able to find the signed file in the same location as the original application. A ‘_signed.sisx’ extension would have been added so that you can easily identify the file you can now install.

ENJOYYY!!!!..
