[Upgrading, Modifying and Unlocking] keff:
Hi fenrir, thanks for the ROM - it leaves a bit more of free RAM and feels faster with graphics (start menu is scrolling really smoothly).

Discovered bugs so far:

Activesync:

- there is unnecessary 'Connect via IR' item in the menu

- after connecting through bluetooth, there is no 'Disconnect' item in menu (it was there in all other builds) - workaround is to disconnect BT from wireless manager EDIT: Disconnect option now appeared - wtf, I didn't change anything except rebooting...

Battery drain after turning on GPS (device.exe has high cpu usage):

- well known issue, solution is to run windows/gpstest.exe and in menu-option-gps set Operating type to 'standalone', Session type to 'nevigation' - this will turn off A-GPS that doesn't work anyway.

- if you want to cook this in the rom, this setting changes keys in HKLM/Software/Samsung/RIL/GPS/

Display artefacts:

- do you overclock in this ROM? Several times I got some part of buttons or other graphics replaced by color noise, I suspect either overclocking or overheating.

USB connect freeze:

As for USB, I made a list of files from /Windows that were in trashcans 28008 and are missing from your rom - I have some old backup of 28008 directories, unfortunately after some use (so there are many files that were installed by apps).

Those are the files that had size 0 after copying, which means that they were 'baked' in ROM since the hard reset:

// those may be promising - please try adding them to /Windows and connecting the usb cable...
