Should I buy the factory unlocked iPhone 5 from Apple?

Or should I buy one of the many listed on Craigslist? It's just they are cheaper. I saw quite a few selling for exactly $650 or less. Reason I want an unlocked one is because I want to use with T-mobile which is only charging me $60 a month for unlimited text, calls and web.

Added (1). Should I buy the factory unlocked iPhone 5 from Apple or should I buy one from Craigslist?

Added (2). I do not understand what Susan has to say. I have a Sprint iPhone 4s activated with a T-mobile sim card and I did not pay an activation fee. All I paid for was the sim card. What I'm asking is: Should I get an iPhone 5 unlocked from Apple or one on Craigslist?

Then I suggest you to buy the factory unlocked iPhone.

A phone is not locked or unlocked when you receive it really. It isn't any good until you have a carrier. Most charge a $35. Activation fee to "unlock" your phone.

Apple does not sell the iPhone 5 factory unlocked (at this time). I'd wait & get one from them personally.

Yes buy factory unlocked ones.

If you want to pay full price, sure.

if you can get an AT&T iphone you can unlock it with your IMEI a new SIM and iTunes here: http://gsmunlocklabs.com/unlock-iphone/

  • Will I be charged a data plan if I buy a factory unlocked iphone? I want to buy a factory unlocked iphone 4s off ebay. I currently have a 3g that's unlocked but I don't believe it's factory unlocked. If I put my sim card into this new 4s will AT&T know and add the data plan? I've heard this can happen before but is it just for people who buy factory unlocked phones through Apple or AT&T or is it for all factory unlocked phones?
  • Will an unlocked iphone 4S work for tmobile if it isn't factory unlocked? I want to get an iPhone 4S and my friend has the iPhone 4 unlocked but i'm worried that if i get it non-factory unlocked it won't work. My uncle tried to do it a couple of months ago and apple said that if it was factory unlocked every time the phone shut off or died it would reset. I was just wondering if the same thing would happen if it wasn't factory unlocked? So if I get it unlocked everytime it will shut off it will reset? That is what i'm worried about.
