Dorm Room Wi-Fi. Not connecting on iphone?

I have had zero troubles with wi-fi connection with my iphone in my dorm room since September but now all of a sudden it doesn't connect in my room. It works great on my laptop but my iphone can never pick it up a connection. If I walk out in the hallways or downstairs or anywhere around campu it will pick it up right away and works fine. It is so frustrating! What is happening?!

How to send as SMS instead of iMessage?

My boyfriends mother recently just turned off his dad plan on his iPhone for some sort of dumb punishment. Anyways, he just turned his iMessage off because switching back and fourth between iMessage and SMS whenever there was/ wasn't Wi-Fi was irritating him. But now whenever I text him it says it sent as iMessage and was delivered, but he never actually gets them. Is there any way to change it so it automatically just sends as SMS to him without having to turn my iMessage off?

IPhones off & need Wi-Fi to work?

My iphone has been turned off from my carrier, the bill is just crazy high so we can't pay it right now and it only will work with Wi-Fi, tomorrow I will be out of town, maybe 45 minutes away and I'm going to need my phone and I'm scared none of the places I'll be at will have Wi-Fi, I know this is a stupid question but I'm desperate and I want to know if there's any possible way I can have my phone working at any time tomorrow

Why does safari on my iphone 5 keep crashing?

I have an iphone 5, not jailbroken and i haven't updated to ios 7 yet. My safari app started doing something weird last night. It will close all my tabs (some of them are important!) and just come up as an untitled page when I open the app. I never fully close safari so I don't know why it's doing this. None of the tabs ever show up in my history either, so if i forgot what they were, too bad.
Also my photos app keeps crashing and all the pictures are blurry. Do I need to update to ios 7 to fix this? Will updating cause me to lose any data?

Is the iPhone 5s worth the price?

So I really would like an iPhone 5s, but my parents don't want to pay the price for the plans that at&t, sprint, and verizon have. My only hope is with Virgin Mobile, since their plans are 30 bucks for unlimited text and data; however, they're phones are no contract so I would have to pay full price for the phone. Right now, it's about 500 bucks. I currently have 300 dollars saved up from tutoring, allowance, and birthday money, and I'm wondering if the iPhone 5s is really worth the price.
