How to check if iphone 5s Tmobile is unlocked (before activating it)

[shankar2]

Hi,

I ordered the iphone 5s tmobile (without contract as the Apple Online store says). The website says the phone has a tmobile sim included.

My question is, can I just hookup this new iphone 5s to my pc and run itunes on it, and it should popup that the phone is unlocked?

I might not activate the phone ie go to tmobile to get a new phone number.

Kindly let me know. Thanks in advance!
