This is a bit late but a well.
I’ve red all the replies and i think there is a fault on the phone. I have a sharp 903 phone and it came with a 64 mb card witch is hardly enough for general use. So I decided to buy a 2 GB card and I’ve had the same problem! When I format the card everything is fine but when I take a picture it takes forever to save. Then when I try to view the pics on my computer nothing seems to be on the card at all. If you found the problem please reply.
Thanks!
