Certificate Question

Hi huys. I am new with the Symbian OS. I just bought a SE Vivaz. I like it very much and i wanted to install some applications. Some worked and some didn't but then i found out the ones which didn't work need a certificate and a key. So I searched the web and found several places to get keys. . I asked for them about one week ago. What I want to ask is, how many days does it usually take to get the keys and certificate? Or is there another place to get the keys? I would really like to install some applications.
Thanks in advance for your answers.

I have applied for a CERT Key yesterday , it says it needs 24 Hours to build it , but I am sarcastic that I will receive it today . I didn't found any other way to obtain the certificate quicker . You Have To Wait
