Problem with upgrading to 1.5 from 1.0 with android dev phone

[AndreS]

Hi,

I recently baught android dev phone. It has 1.0 version of Android. I need to upgrade it to 1.5. I searched for it and came across HTC support site.

http://developer.htc.com/adp.html

Here they have mentioned the whole process, but the problem is that I cant download those system packages as downloads are not enabled on this site.
Does anybody has downloaded packages from this site?
Can anybody suggest any altenative site where I can get these system packages and which is secure?
