Iphone deleted only one conversation?

I have never deleted my boyfriend and I's texts over the past year and a half. Today, i got the "storage almost full" message a few times, but i didn't think anything of it. I look tonight to realize that our entire conversation was deleted! His name was still under texts. Just no texts were in it (it would take too long to clear them all out like that, you would have to swipe to delete)

So is this a glitch? I reset my phone and still nothing… This kinda upsets me… Anything I can do?

I can't update my games on iPhone 4?

I can update all of my apps except for my games. For my other apps, to update them I just tap update. For the games, it asks me to sign into my Apple ID. After I sign in, it shows the sign in thing again.
If you don't know what I'm saying, it looks like this:
Sign In
Use Existing Apple ID
Create New Apple ID
Cancel
So basically, it repeats over and over again.

Gs4 active or wait for iPhone 5s?

I have had droids in the past I had the 1st one to drop then the incredible 2 which I hated. I came to iPhone when the 4s dropped. I've heard so much about Samsung it's peaked my interest. I don't know if I should wait and hope for a bigger better iPhone with the 5s looming or if I should just break for a gs4 active. My past experience with my droids were all the same god awful battery life, and apps sometimes were just plain bad or didn't work. With the iPhone I love the ui and its very easy to work with. The droids seems cluttered. I'm just interested in hearing opinions.
