So im headed up to Montreal this weekend to see some family and i've been waiting so long to find a reason to go up to Canada and buy some factory unlocked iPhone 4's. Anyone know if there is a limit to how many i can purchase, and whether they have placed any limit on the recently released white version iPhone 4? I'm looking to keep one so i dont have to do this jail-breaking and unlocking crap and sell a couple for profit. Anyone know if i'd face any problem buying 4 at the apple store? Your input is much appreciated.
