Hi all,
a nice tool from argv. Available at http://arteam.accessroot.com/releases.html

What it is:
This archive contains a certificate (a cer file) and a key file that doesn't expire and that is NOT tied to the phone's IMEI. This is useful to sign the applications without having to request a certificate (i.e. using the Developer Certificate Request Guide from Nokia and the program "Symbian Developer Services Tool" and without having to worry on certificate expiration. This makes the signing of applications easier. So called ezMode signing.

Usage:
With this Cert.cer and Key.key you can sign ANY app. So, open the BiNPDA SiGN Tool and Browse for your app, then open the Cert.cer and key.key and type 0000 as password.
Then just click Sign and in the matter of seconds, your application will get _signed sufix on your application.

After that just install the application on the phone.
You can install over Cable, Bluetooth or Infrared or directly on-phone where you have transfered your application.

And thanks for sharing the tool also. You might want to create a CRCETL entry for it, before dELTA sneeks in and does it himself.

Regards,

Thanks for the heads-up Shub, as usual.
