Iphone 4s with straight talk?

So i've been researching and i've pretty much come to the conclusion that you can activate an iphone 4s with straight talk.

Can you buy an unlocked phone from apple or should i buy one from att. Although wtih att, a no contract iphone 4s cost the same as on the apple store so sould i just get it from apple. I don't want to pay the reduced price contracted iphone from att because i don't want to wait two years to switch over to att.

And if you can activate the iphone with straight talk do you really need to jail break it. Isn't jail breaking an apple device bad for it? I was going to go with virgin mobile but straight talk is cheaper and has way better coverage. Also people say virgin mobile got a "bad batch" of iphones so their not as good?

Thats why i want to buy the unlocked iphone from apple but it says in the fine print that the unlocked iphone 4s only works with GSM networks and not CDMA networks. Is straight talk a GSM network?
Sorry about the long question but id really like answers from people who use an iphone 4S with straight talk
Thanks

Added (1). Also this is kind of random (and doesn't really matter cause if i can activate it with straight talk i'm choosing them) but what carrier is better for iphone 4s virgin mobile or straight talk?( i don't really care if you answer this question but it would be nice if you did: P. )
