Just rooted my PRE and want to start making some modifications to some of the programs like the Mcraig hack. Before i started i read the applying patches tutorial.

h t t p : / /predev.wikidot.com/applying-patches

Just wanted to know if this tutorial applies to any modification you make to your pre.

For instance, if i decide to modify the mcraig application would i need to run thru the steps in this tutorial. If i ever update the mcraig application via the app catalog would i have to "remove all patches". Apply the update, then re-apply all patches? Or am I misunderstanding this tutorial and it does not have anything to do with this.

Thanks in advance
