I've been reading the reviews on Amazon for the Samsung Galaxy S3 and I want to buy one, but I don't know which one to get.

Here's are the constraints.

1. I don't want a plan or a contract, therefore it must be unlocked.

2. It should work with T-Mobile in the US.

3. Would be nice if I could use it internationally.

I don't want to buy a phone only to find it doesn't work with T-Mobile. I know I should learn what all the different terms mean. Right now it's easier to write a post and ask you guys to tell me what to get. :-)
