If I wanna go back in time

Today is November 14th, 2015. Let's say I wanted to go to an alternate timeline (so I won't be erased or anything) on May 14th, 2012. If I brought with me my iPhone 6, would I receive texts my past self would have received with his iPhone 4c Would I lose my photos on iCloud? Would the music on my Spotify and Music playlist disappear? Would my iOS 9 crash? Would the NSA figure it out? Should I get a fake ID?

I really need to know all this because I have constructed a time machine and plan to go back to the past tonight and need to pack. I moved approximately 2.5 years ago from the west coast to Midwest. I plan to go back in time and give myself a year to get to the west coast and formulate a plan to stop myself from moving. Then I plan to secretly guide my younger self through life while I start a new life in the past. Should I get a fake birthday and secret identity so I can still have doctor appointments in case of health issues? Anything else I should worry about? Is this illegal?

I don't think the NSA will find out, unless you tell them. And if you do tell them, they will probably laugh at you thinking you're crazy. You won't get texts you got from your past self, but I'm about 70% sure your pictures and playlist will save. Your phone also probably won't crash. You should bring a few fake I.D's just to be safe, and pack extra money.

Here's what you should worry about: Once you go back in time, it creates a new time line that is actually different than the original timeline, but this will happen the further back you go. So, when you go back in time, you may find that your other self is female, or has a different name. Not only that, but you will also most-likely age 2.5 years as well. Also, if you see your other self, this will create a time paradox and, well, the universe will end. However, these are all theory's, so who knows.

Last time I checked, there wasn't any laws that said that you couldn't time travel.
