How to save conversation on iPhone messenger?

Lailani

What straight talk phone holds text messages like a conversation like an iphone does? I really want a phone that can hold conversations so I don't have to keep deleting messages. I use straight talk from walmart.
Are there any iPhone apps to record a phone conversation? The police said if I could record a certain a phone call that it will help them a lot so this is very urgent any help is appreciated.
Somehow I lost a whole sms conversation? (iPhone)? I was going to text someone and when I looked at our iPhone conversation it was completely erased?! I seriously don't think I deleted it. Has this ever happened to someone? Can I fix it/bring back the messages:/
My iphone automatically deleted my conversation? So i had a conversation with my friend that had been going on for months now. I woke up this morning and checked for a message from him and THE ENTIRE CONVO WAS GONE. I don't know what happened. I honestly don't even know if he texted me know because the conversation is gone and i don't know when it was deleted. How could this have happened? Does iphone deleted messages for some reason? Or did i just do it in my sleep or something haha.
