I use an iphone 4 ios 6.1.3 version and I want to jailbreak my phone?

I want to know if I jailbreak my iphone 4 ios 6.1.3 if I won't have problem or issues, after jailbreaking it

Unfortunately most jail-breaker's agreed to keep the next jailbreak under locks until iOS7 however they still haven't released it so it may be on iOS 7.1 or a newer sub-version. You're best option would be to upgrade to iOS7 so you can get to the next version quickly

I tried to jailbreak mine and started to have issues with my phone so I restored it back to factory settings, but it's up to you if you want to
