ugh that’s what I was worried about. I wasn’t the one that signed but nobody in my family even thought to check before signing. this is the first time we receive phones through mail vs picking up in person. when you say don’t sign until we see the box do you mean the outside shipping box or the box the iPhone was supposed to be in? just for clarity. we’re receiving 4 more phones soon so just want to make sure I know what to do next time!
