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?

How to help someone gain confidence over their fears?

My best friend who lives in Ireland, & I live in America, wanna FaceTime (video chatting through iPhones). But the problem is being filmed on camera happens to be her bigger fear & I need to find a way to help her overcome her fear of that, & I tried things like:

Talk to a piece of paper thinking its me, & when your done with that, go to talking to a doll, then try talking to yourself in mirror about me, & then go try talking to a camera (without recording) & if that helps any then try to FaceTime me.

I tried multiple things to help her understand that it'll be ok, but I can't find anything. Any help?

Face looks deformed on webcam?

Ok it's not that bad
I'm one of those ppl who aren't photogenic at all partly because my face is a little asymmetrical (my eyes you can't notice in real life which is weird)

I look much better in vid than in pics but still not that great compared to the mirror
So jve been looking better and better on the iphone over the past months I don't know why.
So If I take a pic on my iphone I have this perfectly oval face, even more oval than in the mirror. When I turn on my webcam it just looks oddly shaped it's symmetrical but my jawline looks wide my mom even walked into my room and she's like your jaws and face is much bigger on webcam

All of the other features on my face look alright but what's up with my face shape

How to turn off iPhone with broken lock and screen doesn't work?

My phone's lock button broke a while ago and have been using it without a functioning lock button for a while now. Whenever I woke up, I see everything on the screen and I can get to the slide to power off screen, but I can't slide to power off. I can't slide to unlock so I thought I would try to restart it and turn it off for a while. Is it possible to turn it of with a computer or does anyone know a fix?
