jad files dont open on diamond

[BorisD]

Hey there, so i am almost certain that the reason for this is my lack of knoledge, never the less....

I am running Juicy 2.7 (same percisted with 2.5), sprint touch pro radio... running on telus.

My problem is that when i try and install something such as gmail from m.google.com (through my internet explorer), it downloads a jad file (with the open now function grayed out)... once the file is downloaded, i locate it and try and open in when the diamond tells me
"there is no application associated with "gmail". Run the application first, then open this file from within the application."

Any help is greatly apriciated.
