[SOLVED] J2ME: Application is untrusted and maybe harmful to your phone

J2ME: Application is untrusted and maybe harmful to your phone

I got my R&D signed app from Java Verified submission portal.

I install it on my S40 device and it run fine.

But in my S60 device it show an warning before install: "Application is untrusted and may be harmful to your phone." And it worked like an untrusted app.

I checked certificates in this phone and there are only one UTI certificate: "MIDP 2 GeoTrust CA for UTI". is there anyway to install UTI certificate on my S60 device?

This is my Jad file:

MIDlet-1: hello_world,/icon.png,JDialer.GameMidlet
MIDlet-Certificate-1-1: MIIEbTCCA1WgA...
MIDlet-Certificate-1-2: MIIDzjCCArag...
MIDlet-Jar-RSA-SHA1: lCFSJEHCFKe...
MIDlet-Jar-Size: 171119
MIDlet-Jar-URL: hello_world.jar
MIDlet-Name: hello_world
MIDlet-Permissions: javax.microedition.pim.ContactList.read, javax.microedition.pim.ContactList.write
MIDlet-Vendor: Vendor
MIDlet-Version: 1.4
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.0

Please help me regarding this and thanks for your reading.

Solution

Sr, this is my confusion. I need to change permission to Always Allowed for my app on my real devices manually (new devices have option for this in first time run). I also install jad file instead jar file on remote device in RDA program from Nokia to make my app in 'Trusted Third Party'.
