A Couple Questions Concerning Installer (Not Newbie Stuff - All Ans. Appreciated!)

Ok guys, here's the scenario.

I sometimes sell, sometimes gift iPhones to people that REALLY should not have the ability to uninstall things by accident that they NEED through the installer. If they learn on their own, that's great, but up front I need to know how to do the following:

1. How can I remove the uninstall portion from Installer?
2. If I can't remove the uninstall portion from the installer, how can I make it so that an installed program does not show up under the uninstall? (Without Removing it from the phone)

I know how to remove installer after having put it onto the phone, so that answer is not necessary. Also these are programs I can't install thru iBrickr...so leave that option out of it if you can! I really appreciate your help in this. I want them to have access to the community's great open source work, but I don't want them to be able to uninstall some of the tweaks I need to use to customize their phones.

Before you attack me, I've donated about 150 dollars to the Dev team. So I'm one of "those", but one of "those" that appreciates their hard work.

Please help me if you can!

if your in 1.0.2 installer is simple to delete, it gets complicated with 1.1.1 however because you can't just run apptapp. however, i recommend you just hide the icon, regardless of firmware version, they won't be able to change anything, and if changes need to be made easily, it's possible. :D

Thanks, I appreciate the help.

But that's not what I was asking. I was asking how I get a program not to show up in the UNINSTALL portion of Installer (Apptapp).

I figured there are either two ways to do this.

1) Erase the uninstall ability of the installer (but that I think is foolish since each update would restore it).

2) Erase the imprint that a program makes when installed thru the installer.

This is more promising, but I don't have a CLUE how to do it...

This is where I need the technical help.

Any steps you give me, I understand. I would prefer a phone only based solution (Finder, Squid, Etc), but I can just as easily do Putty/WinSCP/etc.

Again, please help! :)
