It's the same with all storage media. The card has a hidden 'reference' file on it - to tell the computer what kind of card it is, and how much data can be stored. This data file uses up a small amount of the card's memory, and is quite normal.
no only a 2gb
check
It supports 2GB Memory card
check
The microSD memory card slot supports up to 16GB
Yes, a 2GB memory card is included.
1 GB is 1024 MB (possibly only 1000 MB) and therefore is more.
on a 2gb about 40
300
Not much on anything, but that depends on what you are using.
No, the phone can only support up to a 2gb memory card. ANSWER Mine has a 4gb card and works fine! I want to know if an 8gb card works!
Honestly the only difference between different brand cards is the size they come in. What evr slot the Sony camrea comes with you can use any card with. The best sized memory card though would have to a either 2GB or more. you can store thousands of pictures on a 2GB card.
