that's not really as verification for the stock 595 build. i think the article you linked may be older than the upgrade path thread over @ mydroidworld. it's strange, they offer rooted odexed and deodexed 595, but confused why stock 595 cannot be rooted with gingerbreak.
i finally got a clean download of stock 595 and stored it on my sd card. if i knew gingerbreak would work with it, then i'd install it, root it, then simply unroot it to receive the OTA when it's being pushed. but flashing a new rom is always some work, even with titanium backup and mybackup pro, i still have to go in and configure all my settings manually after a new flash. already did this about 3 times so far with 573, 588 3-part and 591.
so maybe i'll sit on this file until OTA is pushed and confirmation of root on it. i guess even if 595 stock can be rooted with gingerbreak, doesn't do anything for anybody if 596 has been patched and cannot be rooted (yet) ....
