My friend (not me) purchased a used 3GS iPhone today, with 2 weeks of warranty left. We're going to the apple store tomorrow in hopes to get a brand new refurbished one, because this has many hairline cracks. We planned to do that anyways. I previously owned a white 3G and replaced it 8 times under the same reason. But the thing is, she is not the original owner, nor does she have a data plan. It does have warranty, but i'm not sure if she is eligible for a hardware replacement.. Can someone confirm? I will provide more details if necessary, but I think that's all.
