Nokia 3250 is in one of my favorite phones and right now I have it, but the problem I'm facing is when I'm trying to installing any application it won't let me 'n give me some "Unable to Install, Unsigned application" error, is there any possibility I can install applications into this.

If you are using one of the extended capabilities then you won't be able to use self-signed certificate. You have to request developer's certificate from Symbian.
One more thing to check, If you open Application Manager. Select Options | Settings. Make sure that Software installation setting is set to "All". If you have "Signed only", you won't be able to install self-signed application.
You can get R&D Certificate from Symbian Signed (http://www.nokiausers.net/forum/third-party-software/10260-symbian-signed-registration.html.
