How to jailbreak iPhone 5 iOs 6.1.3?

I don't know much about jailbreaking. Can't find an easy download. Is there even a download for 6.1.3 yet? Is it worth the jailbreak anyways? Does it void by warranty with verizon?

Jailbreak for 6.1.3 is unavailble for iphone 5 and 4s as of right now. A lot of buzz have been going around on how its released but it isn't. Don't pay for any jailbreak program its a scam! Keep an eye out on http://evasi0n.com/ or http://www.evasionjailbreak.com/

To unlock your iPhone 5/4/4S/3GS iOS 6.1/6.1.2/6.1.3 visit the official website http://www.Unlock-iPhone.org.

Do not listen to the 2nd answer that link asked for money never pay for jailbreak it is free

Well, you can go and downgrade your iphone to 6.1.2 or 6.1(search on google) and then jailbreak!

Oh, no, there's no jailbreak for ios 6.1.3 in A5+ devices! Unless you have a backup of previous firmware, or SHSH Blobs, If not I'm afraid you have to wait for iOS 7, because the developer have announced they have got new exploit, but they will save it to jailbreak ios 7… You can read my source for more information
