I have an application which is running in more than 1000 Nokia C1-01 mobile phone.

Now i have a new version update. User's can select options in the mobile menu and upgrade to the new version of the application.

But immediately after the download is complete, it is throwing an "Invalid Application" Error.

OLD and New [Jad and Manifest] are below.

Note: New Issues with the Fresh Installation and the application is working seamlessly.
Note 2: Application is not signed by any vendor or Nokia (Not available in OVI)


Is the Build properties in Netbeans is causing any issue in this ??

Please help.
