Refurbished iPhone 4, locked or unlocked?

[nardow12]

My brother is looking to get an iPhone and found a girl selling her iPhone 4 for a pretty good price.

The girl says she got the iPhone 4 as a refurbished unit from Apple after her original iPhone 4 went bad, and she have no clue if it's unlocked or still locked to AT&T.

I have heard stories about the Apple store 'refurbished' units being unlocked back in the iPhone 3GS and when they first had the refurbed iPhone 4.

Anyone know if the refurbished iPhone 4 from Apple are still locked to AT&T or unlocked? Thanks

If she had AT&T service, then its most likely a model thats locked to AT&T. The best thing to do would be to call either Apple or AT&T to check (the serial number of the iphone)
