Hi All..I have confusion about amount of RAM Galaxy S has. I have read and known that it has 512mb RAM, but I see a lot of posts wherein RAM shows only 256mb. Any idea why that is? Some comments on other forums show, that Android 2.1 has limitation to access only 256mb and full potential of phone will unleash only when Samsung upgrardes it to 2.2 (Froyo). Any thoughts would be great.
