AT&T Tilt Cab File Help

[Rustys]

I have an AT&T tilt device and have replaced the phone skin on my device by editing the images on the phone. I can manually put the rebuilt files back on the phone without error. Everything works fine. I'v created a cab file install, to change the images in a more automated fashion. This also is working; however, the install is then recorded by the device and with each following install I'm warned of the already existing app. Keep in mind I'm not adding or removing any files just overwriting them. My questions are as follows.

Is there any way to install the files without the device recording the install?

Is there a way to supress the warning messages about the already installed software.

Is there a way to prompt the user to restart the device after an install.

i have never done these things myself (except removing the warning through a reg edit)
but they may be possible through "cab manager" here (http://www.ocpsoftware.com/products.php?nm=cecabmgr)

I am using cab manager to create the cab files, I guess I was hoping someone with more experance with it could point me in the right direction.
