iPhone Jailbreak iphone 4s to ios6

[Ichkamo]

Hi,
I have an iPhone 4s with ios5.1.1 on it. I'd like to upgrade it to ios6, and since apple isn't signing ios6 for this iphone anymore, I wondered about jailbreaking.
Please bear with the fact that I don't know anything about jailbreaking...
I read about two ios6 jailbreaks : evasi0n and p0sixspwn, I'd like to know which one is better and most suited to what I'm looking for.
The only things I want are the following :
- icloud
- appstore
- iTunes 10.7 sync
- well, basically everything a non-jailbroken device has with ios6...
Is this possible with jailbreak?
And if that is so, what is the *cleanest* jailbreak I could use?
Thanks a lot!
Any comment or advises would be much appreciated.

Post scriptum : I have a mac with osx10.9 btw

You cannot upgrade it to iOS 6, only the currently signed version of iOS. At this time, that is iOS 8.1.

Even to a Jailbroken ios 6 firmware?

No, only to iOS 8.1.

And if you indeed want in JB, best itunes restore now to ios 8.1
Apple already seeded ios 8.1.1 and its confirmed that they blocked the current JB. That ios 8.1.1 may be here REAL SOON
