i called applecare directly this time (last time i called the apple retail store and then 1800 myapple). i spoke with someone and they told me that the drive IS upgradeable. i even got a case number in case someone gives me grief. the only problem now, he couldnt order the drive for me, it only showed my original drive. he told me to call the apple store. so i did and they told me they only do repairs, but not the upgrades.
i guess i will try later
