Is it possible for someone to have hacked my iPhone?

I have an iPhone 4 & it has been acting very strange. I'm having problems with messaging. The red alert badge keeps popping up for messages that have already been delivered & in some cases replied to. The person I have been texting also has an iPhone & the messages she has been sending me come in fine but then have the red badge & when I touch it her messages move from her side to the side mine show up on. Also, after this began happening I continued to text her almost 30 minutes went by & then I suddenly noticed that somehow it was showing that an image had been sent to her 30 minutes ago. It didn't look like it normally does on iPhones. It didn't just show a portion of the picture. It looked kind of like it would appear on a computer. It was a white square with a question mark in it & it said unknown next to it. When I touched it it just said the image could not be found. I also continue to receive messages from her that I've already received. This has just begun to happen today. Does anyone know what is going on?

It's possible

We can't tell you if you have been hacked or not.

The reason we can't tell you is we don't know, a fault could be the cause, or malware, the only real solution is take the phone into a apple store and ask them to have a look at it.

Yes, i phones can also be hacked

  • What should I do if someone hacked into my Apple ID? Last night, someone went into my Apple ID. This person sent a plenty of abusive messages to my contacts. I know I didn't do it, because I was just busy watching videos while that person was sending messages. So I have blocked all my contacts to keep low from this person. Well I used to a iPod touch and I lost it last year in my school. After when I lost it, someone must have found it and went inside that account. So is there anyway I can do? I own a iPhone 6S btw
  • Is it possible for my iPhone to be hacked if it's not jailbroken? It's not jailbroken, and I don't let strangers on my phone so no spyware apps were downloaded. Still, is it possible? Sometimes I hear what sounds like a whole crowd of people talking without any apps being open.
  • Is it possible for my iphone to be hacked from a different country? I'm curious. Is it really possible? As in, can the person see the apps that I've been opening and the things I've been doing there? My iphone doesn't have a SIM card in it, but I still want to make sure. Maybe I'm just being paranoid, I don't know. And how would I know if I've been hacked (in my case)?
  • I hacked someone on instagram? I hacked a friend from instagram with my phone because i was seriously mad at him then. Hours later he said that he called the police to find out who it was, i got really scared and almost shat myself. Is this possible? Can the police track down my Iphone and know who it was? I live in Norway btw.
