Downloading problem after signing an app

Hi Guys,

I am into strange problem. I signed my application from thwate. After signing, when i download this application OTA, it says invalid application. Then i upladed unsigned application and try to download ,it downloaded successfully.

Application has been signed properly because on sony ericsson it says "trusted application".

On Sony ericssona and nokia, it download completely and then it says invalid file. But on motorola it says authentication failed before download starts.

I have checked all the attributes in my jad file and the jar size attribute which is mentioned in JAD.

Hoping to get some +ve clue..

Guantana.
