Any Problems with iPhone 5 Jailbreak?

Hi everyone,

I am considring jailbreaking my iphone 5 but first wanted to know if anyone has run into serious or minor problems with the jailbreak that would make me not want to do it.

Also, if I decide to remove the jailbreak will my phone work normally after restoring or do I have to call Verizon to re-activate it?

Thanks!
