hey guyz.... hi... when i upgraded my phone to v8.3 my memory card in the phone got locked up....
previously i have never set a password.. it happened because of the upgrade only... also i could nt
use any other card in the market... phone is not recognizing other cards.. does tht mean i have to buy only
the Nokia card for the phone??? can anyone comment on this... pls

when u put in the new memory what appears? Is a white blank screen?? or does it says something??

i think it's better go to nokia center

try re-update the software even though the problem persist. Format the memory card.
