Anyone know where I might get the latest O2 X3 firmware? I know it's a fairly old phone, but I just got a 4GB miniSD for it (was told it would accept it).

When I go into the camera I can see over 15000 shots available but when I try to save one the card goes to not recognised. The card is read okay as 4GB on my computer and files write to it okay, so nothing wrong with the card.

Thanks for the help guys.
