some people have no issue with updating. however when I go past v 3.0.2.5 I cant restore any nandroids... I freaked out one day... luckily I was able to flash a new zip of "whatever" ROM and then once that was up, I spent a few days digging for answers and it was suggested to flash an older version of CWM through rom manager.. when I did that I was able to restore all my nandroids again... I wont go past 3.0.2.5.
