I need to buy 4 iphones for my business, but I do not want to sign up for the two year contract. I see they are going on ebay for about $500-600. I don't mind paying that much, but I would just rather not deal with ebay auctions. What would be my best bet for acquiring these phones?

Thanks for your help.

There you can find everything you need to know about that subject...

Yes, I have read through that thread, but it looks like at this point it is unknown if that method still works. I was just wondering if there were websites somewhere that sold them or something.

Online Apple Store Hong Kong....
Prices are a bit higher.. but they are offically unlocked..

But they only ship to HK addresses, so you'd have to get someone you can trust to forward them to you..

With all due respect to mojito11 i wouldn't advice an weird sites,some of the weird sites are just a scam to take your money,only eBay,maybe cNet.
As you said the way isn't assumed to be efficient,if i was you i would buy them,and report them stolen after i just bought them(they got stolen on your way back home or something),if you're afraid that they might blacklist you,then i dunno about this,but i'd switch them off,and take everything out of them(battery,sim,and anything that might give them a lead)that way you wouldn't force to have a 2 year contract...
P.S.i know it's not the cleanest way to do it,but if you think about it the other way around...Apple IS being dirty too...
