Can I Switch From AT&T to Page Plus on My iPhone 3?

Obviously, AT&T is just too much. And I've gotten to the point where my mom had to pay my bill and she's not too happy now. She suggested that I switch to Page Plus. Can this be done considering the fact that I'm this crazy contract? Please and thank you in advance.

IPhone 4 randomly shuts off?

I dropped it into the toliet about 3 days ago. (clean water.) And I made the mistake of trying to turn in back on and charge it after, but then put it in rice and sit for a day. Then it worked perfectly fine. Last night it shut off and after a while, it turned back on after I held the on/ff & home button down together for 10 seconds. It's done that 3 times today as well. What do I do?

IPhone 5 YouTube quality horrible?

At the moment I have lte, but most of the time I'm on 4g or my own Wi-Fi. The quality of YouTube videos on the app is pretty much 240p. On other sites the videos are great quality, and it's the same story for videos I'm not streaming. Anyone else has this problem?

New iPhone 4S won't turn on?

Got a brand new iPhone 4S today and even after charging it won't turn on.

I've tried holding down power and home button at the same time and still nothing happens.

When I plug it into my laptop and iTunes tries to restore it I get error "1600".

Has anyone ever brought a Jailbroken iPhone to the AT&T store?

I'm going today, not to swap it cause it's broken, but to renew my contract and get a new iPhone 4. Don't tell me to RESTORE it because I'm not gonna do that. I just want someone who ACTUALLY did this and tell me what happened when you did. Like the response from the store people and stuff. And whether they gave you a hard time when they saw that the phone has been jailbroken.

Would the 500mb data plan be enough for me?

I'm planning on switching to verizon and i'm considering to take the $60 smartphone plan. I have an iphone but i've always had unlimited everything on my previous carriers. So i would like to know if these 500mb will do the job?
What i do the most is Instagram pretty much all day. Rarely post pictures, but i do check my feed a lot. Same thing with Facebook and, Vine. Occasional internet browsing just to check for addresses or googling stuff. Rarely go on YouTube. The email app is there but i don't use it that much.
What do you people think?
