If I sell my diamond

[orangekid]

If I sell my diamond to someone via craigslist can they walk into a sprint store and activate it if its unlocked with a 21882 sense 2.5 rom on it or well the reps by like "wtf is this hideous freak of nature" and tell him they can't do it or give 'em crap about it?

Should I sell it and tell the person to activate it via phone (can they do that, I've only had phones activated in store)

I feel like I can get more $ for it if it's all pimptified with 6.5 sense 2.5 on it.
