Can this iPhone 4s be activated?

Iphone activation help?
I got an iphone from a friend, that got it from Sprint. When there isn't any SIM card in it, the iPhone STILL GETS BARS So when i restore it on iTunes will i be able to activate it without a SIM card?

If it's Sprint then the GSM side is locked. Getting bars doesn't mean anything. It can get a signal but it can't use it.

So in short, no, not unles you get a plan from Sprint.

You will not be able to activate without a SIM. If you want to use it, your only option would to be to go to a Sprint store and get a Sprint phone plan. If you just want to use the phone like an iPod Touch (meaning with no call or cell network functions) then take it to a Sprint store and tell them to just activate the device, but you still would have to pay if you want to get phone service in the future.
