My iphone 5 is showing an unread message although there's no unread message?

So earlier today I accidentally deleted the conversation between my boyfriend and I on my iphone 5. Since then I started having problems. I would read his message and respond, and then I would pull down the task manager and it would give me all the texts he sent me, and implying they were unread. Somehow the conversation was deleted again (99% sure it was not me this time) but not my phone is telling me i have 11 unread messages.

I have tried resetting it, many times.
I have tried the sleep button and the home button reset.
I have tried updating the software.
And because the conversation was deleted, I can't go back and read them because they are gone!
Nothing is working.

Is an unlocked iPhone 5, iPhone 5c and iPhone 5s truly unlocked?

I had previously asked this question before but those who answered didn't actally attempt to comprehend the question, even with two additional updates added to the question.

I completely understand how unlocked phones work but the question I have is how do unlocked phones function when lost/stolen or in an insurance claim - go unreturned?

Well, the reason I ask is because I originally filed a claim with an Assurion for defective iPhone 5c. This was previously replaced by Assurion and is confirmed to be refurbished. Well, the device went missing after the filling of the claim. Unfortunately, since this claim is "Completed" with Assurion it can't be modified. Which means, Assurion is expecting a device be returned that we don't have.

Unfortunately, I do not have too many details beyond that this particular line doesn't belong to me.

Per Assurions policy, if a device is not received within ten days, they will charge the payment method up to $300. Unfortunately, that appears to be the only route. We're concerned/curious even more so because the device is unlocked. We want to know if the device is ever recovered, will it still work? So since this will technically this will be an Damaged Device not Lost/Stolen…

Does anyone have any experience with this? Will the MEID be blacklisted, is that even possible because the device is unlocked?

We want to recover as much of these expenses as possible…

Can I connect two extention cords together?

Purely for cosmetic purposes. I only use it for two 3w lamps and my iPhone/ iPad/ macbook charger (one or the other, never all at once). Could I have the two lights in one extension so that it can be hidden behind my bed with another extension coming off of it to plug my phone in to?

I found an iPhone what should I do?

So today I was at this thing that took stuff for recycling and found this old iPhone. I was really excited for some reason and kept it. I know I shouldn't have but I did anyways. I got even more excited when I could set it up and make it my own. I know, I know, it was a really bad thing to do. I have it now and it's set up. I'm not making any calls or messaging people, but if I did, what would happen? I'm really worried and wish I didn't take the phone. I can't bring it back because the sorting was finished and everyone went home. I'm a very paranoid person, and I don't want to get in trouble with the police or something. What should I do?

I really wish I didn't take the phone. It wasn't mine and it was for the recycling project.

Does something like a sword or a water bottle count as technology?

When we think of technology, we think about things like iphones, laptops, stuff like that, but back then, didn't the bow and arrow, sword, even a stapler count as technology/

I mean a bow and arrow or sword made it easier to kill animals for food than with our bare hands and a stapler made it easier to bind stuff no?

IPhone 4s won't connect to internet or Wi-Fi?

I have an iPhone 4s and I have literally tried everything to try and get it connected. I have restarted the phone using the lock button and home button, I've reset the network settings, even put my sim card in another phone and the exact same happened. It won't pick up my home Wi-Fi either! I called EE and they said it was my phone causing the problems but I have an iPad mini that is working fine but doesn'y pick up the Wi-Fi either. When I leave the house I just get no service at all, someone please help I've exhausted every other option.
