Is T-Mobile blocking Google on Nokia phones?

Nokia phones on T-Mobile's network have suddenly lost the ability to connect to Web sites requiring SSL connections, such as GMail and Google Reader. Is T-Mobile really hobbling Nokias? I carried out a little test using three phones and two SIM cards to find out. You can find more info on this problem here: http://mobilementalism.com/2008/08/27/t-mobile-hobbling-nokia-phones/
