Which is better.iPhone 4, 4s, or 5?

So with all these ugrades we're getting through Verizon and such. I'm going to get a new phone- either the iPhone 4, 4s, or 5 and I have heard that the 4s is having some problems i don't know.
But heres the deal.
its free to get the 4 (plus $30 for the upg.)
$50 to get the 4s (plus $30 for the upg.)
$100 to get the 5 (plus$30)

On top of that my dad has some sort of theory that I also should pay for the phone itself because i don't know haha but anyway its going to be around $180 in total for the 4, $250 for the 4s, and $330 for the 5.
And with the iphone 5 being such a great deal i don't know but I don't want to spend all of that money to get a phone that's barely better than the first two.
Is the 5 really worth the money?
Which one should I get?

My iPhone 5 will not connect to the internet unless on Wi-Fi (T-Mobile)?

So my husband and I have had T-Mobile for 3 days, surprise, we have had issues every single day. They were resolved, but now we have a new one. So we have good coverage in our home… Sure it goes between 4g and "E" (which is annoying but whatever), and are able to make calls, texts… But unless our home wi-fi is on, we can't get on the internet with our phones, at all. Even when it does say 4G. Anywhere else we have zero problems. He has the new Blackberry z10 and I have the iPhone 5.So I'm doubting it's a phone issue, more or less a T-Mobile issue. Of course, I chatted with someone online, he tells me to call *611. Oh well, surprise, "all circuits are busy, please try again later -click-* Well that is just lovely. Anyone else have this problem?

To be quite honest, if we thought the only way to use our phones was by wi-fi when we're home, we would have never switched to this stupid company…

And YES, we have unlimited talk, text, data… Like I said, it works fine when we're not in our home lol. Go figure right? I don't have a problem using my wi-fi when I'm at home but I just think it's silly that that is how these phones work… And if I have a problem with my wi-fi (like I did this morning) then our phones won't work.

Last night I had the problem of my picture messages not going through… It's pretty sad that Googling the problem found me a solution. Customer service here sucks.

Why does my iphone 5 charge so quickly?

I got new iphone yesterday… I used it for 4 hours straight and it was at 30 percent, so I plugged it in. It only took one hour for it to go from 30 to a 100% charge. Why is that? I have never seen something so awesome happen

Why do i receive mms as a link in an iphone?

I have an iphone 3gs… My carrier provider is airtel… I called them up and asked them to activate mms for my iphone… From then on i'm receiving the mms in a link… When i click on the link it redirects me to the web broswer where it opens there… So my problem is that why don't i get the mms as a pic in the inbox…
Thanq…
