About a week ago, I went to the Sprint store, and traded in my iPhone 6 for an iPhone 8.
They told me that they wouldn't erase the data on my existing phone for a few days in case I noticed that something didn't transfer correctly from the 6 to the 8.
Today, they called me and told me that they couldn't erase the data on the iPhone because they couldn't get past my lock code. (For the record, I told them I'd swing buy and unlock it myself.)
This situation doesn't make sense to me because everything I've read suggests that it should be possible for a savvy user to erase data on a phone even if they don't know the lock code, and furthermore, I would have just naturally assume that a brick-and-mortar smart phone store would have the capability to erase a phone that had a lock code on it.
Does their ask make sense? Would a sprint store need a lock code to erase the data on a phone?
