Can an iphone be stolen from the mail?

My boyfriend ordered me an Iphone 5s Wednesday, he did overnight shipping so it'd get here faster. When Thursday came, he called in to check to see if it arrived and when he did he said it hadn't made it yet. But when I checked the tracking info it said the phone had already arrived. Wtf? He said he'd keep me posted on it, but it's Friday and he hasn't said anything about it. Does it sound like my phone was stolen? Like are iphones shipped discreetly in like brown boxes or do they get shipped in the white iphone boxes you see people on YouTube with when they do the unboxing videos?

Added (1). Also, my boyfriend was at work when the phone arrived but on the Fedex tracking page it said it was signed for by someone else. My boyfriends name is Danny Taggart but it was signed for by someone named "D. Walton"

Can I swap/trade/sell this iPhone 5s case?

I have a brand new unopened lifeproof case and I want to trade it for a mophie case (they are the same price) or sell it in store. I got it from lifeproof.com so I'm not sure if I can go into a store like bestbuy and ask if I can trade it.

Can you delete iMessages without entering the app?

Okay, this will sound really dumb, but I copied and pasted a word so many times and sent it to a friend, then now whenever I enter iMessage it freezes and exits out of it. So, obviously I'm trying to delete the message so it gets out of my phone but it's freaking out and won't let me! Please please help!
( I have an IPhone 5c)

How to get my stepdad to buy me an iPhone?

I know this sounds pretty stupid but how can I get my stepdad to buy me an iphone? He bought his daughter a gold 5S yesterday and I'm pretty jealous because I would at least like something similar. I don't have much and my mom doesn't wanna spend $600 for a phone. I receive good grades and she does "ok" in her classes. How can I convince him to buy me one without asking and sounding stupid?

What iPhone 5 plan will give me plenty of data cheap?

I'm about to be in college so I don't have a lot of money. I have an iPhone 5s on my mom's plan, but I plan on getting my own and I need to know what plan to use that will give me plenty of data (3GB or more) but won't cost entirely too much.
