Safe deletion of native Omnia applications?

[arizonaomnia]

I've had my Omnia for a little more than a month, and while I'm a power user by the average person's standards (I LOVE Spb Shell & am now, thanks to you, successfully using GPS with Google Earth), I'm a bit of a noob with WinMo, having spent a number of years on Palm OS until recently. I'd like to clear up some Storage memory, and while I understand I can't uninstall Mobile IM and VZNavigator and the like, I'm wondering what would happen if I simply deleted their program folders (as if I am on a Mac, I suppose, LOL). Or is there a better, noob-friendly method of uninstalling native applications?
