very nice job Konstat!
I wonder if JB requires bigger system partition like ICS did. what the say regarding this?
I guess it only depends how much you're willing to trim it down.
I've already applied my CM9 trimming strategy to CM10 and system size for the ROM that comes out from the build process is now ~129mb. There's still some stuff that can be removed (and stuff I need to add back if I ever release it) but it is probably by 5-10mb larger than ICS. Gapps for JB are also bigger, but I have no idea how they even work on our device (haven't tested yet, I'm still running 138mb system partition). With some trimmed gapps smallest possible system size will probably land somewhere between 138mb and 160mb.
Anyway, it's way too early to start TPTing for JB.
guys take a look at this, http://maclaw.pl/?p=205
the dev said that project butter has worked (100%) and it's on a qualcomm armv6 device
It's also funny how they say "IF YOU WANT TO USE MY WORK, YOUR WORK MUST TO BE OPEN SOURCE TOO!!!!!" in their thread, but their sources are nowhere to be found.
