Did that, no effect on HC, flashed back to Gingerbread, installed the apk's, nothing, edited the prop file, nothing.
Well, not quite nothing, I figured out that on launch, it seems to swap the walpaper, which leads me to believe it's doing "something" but something is also not being triggered, there is a OOBE (out of box experience) apk, but it only installs, it doesn't seem to have a way to launch, dunno if maybe that's the issue.
Shame... I tried the zoodles interface, it's crap. I just want a simple locked down interface for my 3 1/2 year old to use on my gtab.
