I too would like info on this. I'm wondering if its at all possible to alter the update script to install 3rd party apps into /data/app and /data/app-private. I've tried placing 3rd party apps into one of the Dude's roms(i think, can.'t remember exactly which rom it was), but I didn't install my 3rd party app. Yes, I did resign the update.
So if someone could help me with this, i would be really grateful. I'd like to make one script to load just /data and another to be included with my usual update.zip's.
I really enjoy the fact that my phone is so customizable, but those 3rd party apps make my custom themes sooooo ugly. i don't mind taking the time to pull apps and theme them, but reinstalling them is a pain. I know there is a windows utility for reinstalling apps, but I'd rather just flash /data.... is this even possible?
Anywho, if any of you "smart" guys around here could help me with this, I would be such a happy droid.
