also have to factor in the eBay and PayPal fees. here is an easy way to calculate how much profit you can potentially make after figuring the fees

Thanks to all who replied so far.
Ok so to 'avoid' any scammers, i thought about not shipping internationally, but that wouldn't make any sense since the unlocked iphones are widely available in canada. the money is all overseas! so i'm going to take some extreme precautions, including:
-only allowing members with greater than 10 feedback to bid, otherwise i'll cancel their bid
-only allowing people to bid who have been ebay members BEFORE apr 2010 (seems like a reasonable time frame)
-ship with tracking number, signature required
and finally, on the day I ship the iphone, (to be able to fight any ebay disputes) i will carry my vid. camera with me, and have my friend record me showing that it is SEALED and Brand new in box (10 feet away from the post office), and also weigh it on a scale to show the exact # of grams it weighs, proceeded by packaging it right there and showing the mailing address clearly, and handing it to the post office. I think thats pretty much a 'foolproof' way to avoid being scammed.
The only think i can think of, is: what if the scammer does return back another phone in the same box, etc.. and ebay would obviously side with him, and after i show them my video, what if they say something like: oh, the box wasn't brand new.. you opened it, put an old phone in it, and taped it up with a small piece of tape along the original packaging.
So the only way I can think to avoid that, would be to actually open the package, which would not make it "brand new in box" anymore, and might lower the auction value?
What do u guys think?
EDIT: Also, i realized if i buy the phone, for say, 600 + tax.. lets make that 700 (approx.). And i sell it on ebay for approx 1400, so there's 700$ revenue. Minus ebay/paypal fees, free shipping, so like, subtract 100 max, right?... so i'm left with a 600$ profit?
