I plugged my wife's new S2 into the computer tonight for the first time and got a notification on the phone, "MTP-connected." Her phone then opened a window on the computer (Win XP) showing me folders for "phone" and "card." I understand what I'm seeing, but I don't get that on my month-old S2 at all. Instead I get the classic "USB connected" and the button to switch to external storage. We both have the same exact specs in the "about phone" section. Anyone know the big advantage of the MTP thing? And why wouldn't mine have it?
