Photo editing app for iPhone?

Okay, so I've seen on Instagram there's some pictures that let you layer two and make the topmost layer transparent, and I was wondering what app it was? I have a picture screenshot, but I can't post it. :/

I'm having an iphone problem?

My cell phone had a crack in it and my dad decided to bring it to this guy keep in mind that before i had my phone fixed the service was excellent, i had the best service but anyways i wait about two days to get it back and one thing i notice the service bar is only one to two bars almost everywhere i go it wouldn't change unless i was near a cell phone tower. My service changed for some reason so i called my brother and told him that, He said that while the guy was fixing it he could of moved or touched my antenna inside my phone while fixing it. So is that true? Could that be the problem to my horrible service because again it was great before i got the phone fixed.

I know who stole my iPhone 5. How do I get it back?

My first time going to this YMCA, and I went to go hide my phone because this YMCA has no lockable lockers.(they have lockers but you have to buy a lock) yeah I get that it was stupid to hide my phone in a gym. But I did it anyways. I made sure no one was looking. Then later I go check and GONE. Right after, I asked if anyone saw who took it. We know who did but he left. So I was PISSED. They said he was sitting down against a wall. And got a glimpse at the iPhone and snatched it.

I went to the front desk to file a report. I used find my iPhone but it was offline. ( thief turned phone off ) I filed a police report, gave them my serial number for the phone and the phone number. I went home tracked it again and it said it was turned on at an address. (I was gaining confidence) then went to the the house with the cop to find out the house was vacant. F. UC.K. I was so pissed. The guy who took it probably went there turned it on at that house that was for rent.

So yeah we know who took it and when i see him at Y what should I tell him? (Btw he's 6'4 and strong, and a pothead)

Also if he sold it how could we prove?

And if the consumer try's putting the phone on a network will it be denied?(since I turned in the serial number to the police)

PS I have two witnesses
Could I take him to court.
How could I prove?

Sry if this didn't make sense it's late and I'm very mad. Worst birthday of my life. Btw I'm 16

AND IT WAS MY BIRTHDAY THE DAY BEFORE THIS All HAPPENED. F. M.L

Added (1). Cruel world and this is one of the first times someone has stolen something this expensive from me (650$). TBH, I've never stolen anything or put down someone in a harsh case. This sub question has nothing to do with the ones above, … But, do you think this world is coming to an end? As a strong Christian I'm questioning God why all this horror is happening in this world? (9/11, Boston bombing, Columbine, Sandy Hook, and many more) I'm starting to loose faith.

My family told me it used to not be this violent 30-40 years ago. Is that True?

Can't send Texts or calls to only one person?

So me and my friend have been texting and calling each other fine, till recently. For over two weeks now I can't send him texts or call him. He also can't send me texts or call me. When we do send texts it says they are sent, but neither of us receive them. When I call him I get a computerized voice in Spanish and when I translate it (i don't speak spanish, but he does) it says "what are you trying to call? 81 80." When he calls me it rings for a second or two and hangs up. Help anyone? I have AT&T and an old flight 2 phone. He has an iPhone, but I don't know what carrier. Do you think one of our parents blocked us or either of us accidentally blocked each other?

Qr code issues on business cards or other small items?

I have an issue where the simple QR code on my business cards is not being read. I think I know the answer but I would like some clarification so I can make the correct changes.
The square is a little less than 1'X1' my 3G Iphone won't read it, but will read other sizes fine.
Is this too small? Is it my phone's camera?
Also, there's a glittery finish on my cards and I'm thinking the texture isn't helping.
I'm designing my cards myself so I can make adjustments. There's a little bit of wiggle room if I need to make the square a bit larger. I don't want to have to go too large so the square overwhelms the whole card.
Any input will be extremely helpful. I'm going to try and make a jpg I can upload with the shiny finish.
