Ok so my service at the moment is verizon wireless.

Good portable iPhone charger?

I'm going on a trip to Disney World in May and I'll be out in the parks for like 12 hours a day. My plan is to vlog while I'm there, but I don't want to bring my camera and I just wanted to use my iPhone, but I know the battery won't last me that long. Are there any reputable portable chargers for the iPhone 5 that I could use?

Good camera to buy for really nice pictures?

I love photography and taking pictures. I want to be like those tumblr girls who take all these amazing pictures with several settings and mods, and a 5mp iphone camera just doesn't cut it. I really want a good camera, but I literally know NOTHING about cameras specs. The only thing I know about cameras is the higher mp, the better. I know how to work one; just not determine if one is good.

What are some really nice cameras to buy? I don't want a $1000 camera please though. Something that's good, but not that expensive. Maybe around $500 and under… The cheaper the better of course.

How to cancel my grandma's 3g plan on her iPhone for AT&T?

Well my grandma came home complaining about me using her iPhone and using her 3G. She said AT&T has detected that she is using a smartphone, and now they added 3G to her plan for $20 - $30 per month.AT&T doesn't have the right to do that right? I mean she never uses her 3G plan but she is charged $20 - $30 on something that she doesn't even use. I have only used her iPhone to download a game from the app store once and they charged $27 for that. I asked if she could take the sim card out of her iPhone and put it in one of her old phones but she won't do it she is as stubborn as a mule and all she does is call on it. So can anyone help me cancel this AT&T 3G on her phone? I mean she doesn't use her iPhone for anything other than calling.
