Bought an iPhone Handset 4 off amazon and it is locked to Tmobile

I just bought an iphone 4 off amazon which didn't state that it was locked to Tmobile - Have rung them up and explained and they say they can't help me because I'm not a previouis customer - they said I need to contact the guy I bought it from to get their Tmobile account details to unlock it!

This seems so dumb as I'm sure people do this all the time… Is there no other way? I've already paid for this iphone it seems so much hassle I just want it to work!

There's nothing you can do. Just call the guy and threaten to put a bad rating on amazon because it's locked. Maybe you can even get some money back.

Warning: All unofficial Iphone 5 equipment is ALSO locked. They have chips in them which allow you to only use the expensive apple products.

The thing about amazon/craigslist/ebay… You have to be careful! Don't ever buy it unless it says CLEAN ESN next to the ad! What network are you? If you're sprint, I know they won't let you even use it at all because it's tmobile and not actually purchased for sprint. ATT and Verizon I'm not sure about. If it's locked to a certain network (like tmobile) then it can only be used on tmobile. But if it's still active to the previous person's account, then yeah, you'll need to contact the seller and have them call tmobile and deactivate the phone.
