Straight Talk PhONE Iphone 4?

So i'm looking for a iphone.
I have no contract and i had a phone before with straigh talk (android) and i loved it.
I live in the country and it got great bars and everything.

However. I was told iphone might be different.

I'm gonna get a phone of ebay with at&t because you can switch it to straight talk for $0

So is iphone 4 or 3 good with straigh talk.

If not. What are some good phones.

My Iphone 5c screen cracked, can I fix it myself? Or too risky?

Is it too risky to fix my own Iphone 5c screen? I was just wondering if I could just pay 15 bucks for a new screen on Amazon/Ebay and fix it myself instead of paying 150 bucks for someone else to do it correctly (and not even you never know if they do it correctly) or is it difficult to, and way too risky?

Which do you believe to be the BEST Final Fantasy title of the series: VI or VII?

I just stumbled on VI on the iPhone and bought it since many people hail it as the BEST Final Fantasy of the entire series. I always though VII was supposed to be the best, but I guess VI is a worthy competitor?

I've never played VII, thought I've really been wanting to. The only FF games I've played thus far is VIII, X-2, XIII, and XIII - 2. I own VIII, XIII, and XIII - 2, haven't beaten them haha. But I'm making my way!

Anyways, which do you think is the best based on plot and characters -- VI or VII. I just started VI and I'm liking it so far.

Can I use What's App on iPhone with no data plan?

I have been using What's App on my iPhone 4 in California for a couple of years now. But when I moved overseas last year, I cancelled my phone plan & have continued using What's App when I'm connected to Wi-Fi.

However, it suddenly wouldn't connect today (Just kept saying "connecting…"). I deleted the app & re-downloaded it. But now it won't even accept my phone number. Just keeps saying "Could not connect to WhatsApp service. Please try again later." The Wi-Fi is working perfectly for my other apps… What is going on?!
