It's only been a few days since the Galaxy Tab 10.1" hit the retail streets here in the U.S., and yet it has already been rooted, clockworkmod has been ported, and now, it has received it's first custom ROM. XDA Forums member Boushh has taken the stock ROM and rooted it, as well deodexed it for faster performance.
Installation is as straightforward as flashing any custom ROM via clockworkmod. There is one small issue with needing to delete some odex files, but it's pretty easy to handle.
For more information on the ROM, head over to the source link below.
