Should I get another iPhone?

I'm eligible for an upgrade for a new cell phone. Right now, I can't decide if I should get the same brand I currently have or try something new.

I currently have an iPhone 4s. I have really enjoyed the phone so that I don't have to juggle an iPod and cell phone. I use iTunes a lot (I have bought over 500 songs. When I add the songs I have on my computers library, I have over 3, 000 songs).

I don't text or call people a lot on my phone.It's mainly for internet, email, and music.

I was considering another iPhone, but I wanted other people's opinion. I would love to have the same phone but with a bigger memory since a 32 GB lasted me only a year (I'm currently on a replacement, but the memory is going down again).

Any opinions on phones?

Iphone case won't fit properly?

I have bought a gel iPhone 4 case that almost look like this but its not completely the same its just to give you an idea of what it looks like: http://killthemwithcuteness.com/jelly-belly-scented-iphone-5-

But the problem is that it won't fit on my iPhone 4s. Yes i know that you should prefereably not buy stuff thats not ment for your model of iphone but i couldnt find the right one. The case doesn't fit on the iphone 4s or my cousin's iphone 4 (on which the case is suppost to fit). You cab put the phone inside the case but the sides of the case don't cover the phone like its suppost to. Is there anything i can do make make it strech out or something to make it bigger? I know its a pretty weird question but i really need to know! (Remember its a flexible gel case)

IPhone 4S screen not working but was making noises?

My iPhone 4S screen is not working; nothing has happened to it, (no water damage or anything) but I put it on standby (pressed the sleep button at the top, as I always do) and when I came to use it again, there was only a black screen. I thought it had only run out of charge as it was running low on battery before I put it in sleep, but I accidentally held the home button down while plugging it in, and heard Siri come up, so realised it had not run out of battery at all, but the screen was not working. I have tried to sort it out via my computer and tried to reset it to factory setting in iTunes, but I don't believe it worked (there was some error or another which meant it failed to reset it, or something) and I decided to try letting it run out of battery, but when I came back to it today (this all happened yesterday evening), there was no noise or anything on the screen. I have tried charging it, but there was no evidence of it turning back on (either visual or noise) so I think the sound may have gone too. If needs be, I will take it into an Apple store, but I will not be able to do this for at least a week.

IPhone 5s randomly stopped connecting to LTE on Verizon?

Up until a couple days ago, my phone received LTE just fine, but one day I woke up and my phone only displayed the 3G icon. I know it's not my location because I've driven all over the city and I haven't gotten LTE anywhere. Is there something wrong with my phone?
