Iphone 4 randomly not working at all. Won't turn on

It will turn on to the home screen for like 15 seconds if it's plugged in but it says December 31 2010 at 4:00.It won't do anything else. Have tried to reset it. I have no clue what happened, It was just all of a sudden! How do I fix it? Any ideas?

Problem with Internet explorer

Out of nowhere whenever I try to open Internet explorer it takes forever to open, then it takes a bit to load, then it's just a white screen and something pops up saying, "A problem displaying google.ca caused Internet explorer to refresh the web page using Compatibility view"… Google is my home page. I've tried clicking everything and nothing will load. I've been looking for that ripped paper icon but its not there. No clue what to do and I really need my laptop right now. Anyone know what this is? What can I do?
P.s.asking this on my iPhone

I ordered something from amazon and it was shipped through Japan post?

When can I expect my package? It hasn't updated in a few days. And I've never order something from an oversees shipper so I'm not sure how long it should take.
(I'm not sure if the size matters but I ordered an iPhone case)

Weird mysterious iPhone call?

A stranger called and left a message on my iPhone, and the iPhone is saying that the number is my girlfriend's, but it couldn't be because she was sitting right next to me with her phone and made no outgoing calls. Is this a bug on the iPhone about the caller ID/what could this be?

How to internationally text from iPhone?

So I leave for spain tomorrow (from US), and i want to be in contact with my family, twitter, instagram, etc. However, i'm not into running up my bill just for my social needs. I downloaded the app heywire because it say i can text internationally from it and it is free, however i don't understand technology very much and want some answers.
1) if people text me on the number from the heywire app, is that free? Or do they need to get the app as well?
2) it says i can call from the app… Is that going to cost money like making a call regularly would?
3) i was told that if i'm on Wi-Fi, iMessages will send for free because they are through 3G usually… Is this true?
4) if i'm on Wi-Fi, will my twitter, instagram, vine, etc work with no extra charge?
