I want to add an auto-updating feature to my SmartPhone app, iPodderSP.
I have managed to get as far as checking an RSS feed for newer versions
and downloading the new .CAB to the phone. However, upon shelling the
CAB via the CreateProcess P/Invoke, I get a message saying
"Installation failed. The program or setting cannot be installed
because it is not digitally signed with a trusted certificate."
This seems strange as I can copy and run the CAB file on the phone
(from File Manager) with no problem. Why does a locally running app not
have adequate permission to do the same?
Does anyone know how to sign a CAB file? I've been Googling for a while
and am yet to find a good solution.

Any help would be great,

- Andrew

Whoops, it turns out the file was not being downloaded where I thought!
But for some reason the OS didn't mind trying to invoke the
non-existent CAB file and reported a rather misleading error message :)
Typical: I spend a few hours fighting with it, give up and post here,
only to solve it myself a few minutes later!

People running iPodderSP can expect this new version to be online later
tonight...
