Why do playlists on my Iphone keep messing up?

I have an Iphone 5, there are some playlists in which I try to rearrenge a song, and after I save the changes, the song moved to a different position. This appears to happen on AAC songs that I converted from itunes, I did this because Itunes suddenly stopped allowing me to change the name of artists or songs. Any idea of why this is happening? Is there effectively a relation between the AAC songs and the bugged/corrupted playlists?

IPhone 3GS headphone jack only plays through one earpiece?

The music only plays through one side I think it's the left. When listening to something it only plays through one side of the headphones over head and and in ear. The headphones I use are terrible anyway but with a 200 odd pound device this shouldn't be the case. It I twist it and hold it in place it plays through both but the headphones work perfectly fine on my laptop so I'm guessing it's my IPhone 3GS jack. It seems quite typical of Apple devices as its happened to my iPod 2nd and 3rd gen, my friends iPhone 4 and now my iPhone 3GS.
Anybody know how I can fix it myself or something along those lines as I don't have £20 or so lying around to get it fixed professionally.

How to tell if my iPhone stolen?

Can I use text/data in Canada on a Straight Talk Unlimited International Plan?

I have an iPhone 4S with a Straight Talk AT&T SIM card. In a few months I'll be going to Montreal, Quebec for a few days. On Straight Talk's International Plan they specify that international calling is available, but they do not specify if text and data are available internationally.

Clarification would be nice, thank you.

Why does my iphone 3 not deliver my messages?

So i keep sending texts but it keeps saying not delivered. I try again and it says the same thing. At the top it says sending, but it stops a little bit b4 getting to the end and says not delivered below my text. I can still make phone calls, but this happens with texts. I've also dropped my phone like 4 times but none really damaged it. It started not sending this morning. Last night it still worked fine. So what do i do, Please Help!

Iphone jailbreak var/mobile/. Photos?

My iphones jailbroken and i was wondering do photos i download using a google chrome downloader have to be in a certain folder to be viewed in the photos app?

I don't want specific photos for my work to appear in the photo app because thats where i have my family photos etc.

Don't ask me to make a picture folder and put it in. I'm trying to make the picture NOT appear anywhere except when i ssh into the phone through pc or i file to see it

Added (1). I think the first answer misunderstand what i mean.

Basically if i ssh into my phone and put a photo in

var/mobile/documents

Will it show up in my photos app? I don't want it to but i want the photos on the device as i like just using my phone for my work images

Added (2). EDIT: the answer is NO photos in var/mobile/documents don't show up in the photo app

IMessages consistently going through as text on iPhone?

This just happened last night. All of a sudden out of nowhere my iMessages started sending as texts and it's STILL doing it, I don't get what's going on! I took it to Verizon and of course they know nothing. I reset my phone, went through every option available but nothing! It's still doing it. What is going on and how do I fix it?

Added (1). Clearly you arent understanding. Everyone I message has iMessage on their iPhone, how do you think I noticed this problem in the first place…
