Can somebody hack my Wi-Fi with their jailbroken iphone?

I was just wondering because my neighbors have a jailbroken iphone and I just to know if they are able to hack my Wi-Fi. My Wi-Fi is also protected.

I think that there will be a very slight chance to hack your Wi-Fi through Jailbroken iphone if your Wi-Fi security is WEP. But, if you have WPA2 then trust me, they will not able to hack your Wi-Fi till iPhone 20 releases and ultimate Jailbreak is formed or something like that.
