Jailbroken iPhone 5 died not sure what my options are

so my iphone 5 died not sure what to do
it stopped powering up after trying many lightling cables and it only having intermitent charging a few days ago i assume its a problem with the lightning port
i took it to an apple store and they said they will replace it and are not sure why it stopped powering up, i told them id think about it and come back

anyway the reason i have the dilemma is all the replacement iphones have 6.1.4 and i need to jailbreak its at the point where im considering moving back to android.
should i move back to android? hold out for a new jailbreak?
would shipping it back to apple possibly get me a old enough one at this point?
is there anyway i can call up and request one thats 6.1.2?


thanks
