I've moved from the Pre+ to the Pre 3 and I had the F1xx kernel (can't remember the exact one sorry) on the Pre+. When I gave the Pre+ to my girlfriend it wiped all the apps off it (of course) but the kernel remained.

Now I'm not surprised by this but what I'm concerned about is that if I put Preware on the Pre+ it's not going to know that this kernel is installed, is it?

Is this a problem? Should I install preware, install the stock palm kernel, and then the custom kernel again just to keep the integrity of Preware's package system?
