Failed install of Tomtom Mobile 5 on HTC S710

[Guest sgilder1]

I am struggling to install TomTom Mobile 5 on my HTC S710. The Autorun app just reuslts in a spinning busy icon, and the EXE in the TomTom directory results in an "application not signed" error.

I have application unlocked the phone by running Prosper's application unlock CAB. I can access previously restricted parts of the registry, and MicroSoft's security device manager says "Execution allowed" for unsigned apps.

What is going wrong??!!

No ideas? Am I executing the correct .exe (TomTom Mobile.exe in the TomTom directory)? Any reasons why my S710 might not be application unlocked (as this seems to be the error)?

Any help would be much appreciated!
