Jailbroken iphone Wi-Fi

So, my cellular data just turned off because its reached its limit for this billing cycle. Right now, my phone is jailbroken and i'm connected to my home personal Wi-Fi. Is there anyway or any app on cydia that will let me stay connected to my home Wi-Fi while i'm out in public? Or some app that will always let my apps like kik messenger work where this is no available public Wi-Fi.

NO, You can't be on Wi-Fi where there's none, Wi-Fi is a medium ranged radio signal not magical.
