Why won't My sprint iPhone 4 won't connect to 3G?

Before you say call them I already have ok. Today I had an upgrade but my aunt used it for her phone since I'm on her plan. It went good but then won't connect to 3G after that we called and they said something went wrong but nothing did so I'm wondering is there anything i could possibly do to fix it or should I call the place that did it? Or should I just call sprint or apple? Please help I have to use my phone a lot in places that don't have Wi-Fi.

Should i buy my iphone 5 a screen protector?

Well, i have an iphone 5 and i also have 2 cases. An otter box defender and some other incipio one that is thin. The otterbox has a built in screen protector. But the other dosnt.sometimes i like taking my iphone out and using it withought the otter box and use it alone or with the incipio (incipio dosnt come with a screen protector).so should i use a screen protector with the otterbox? That means i will have a sticky screen protector and a built in otterbox one (when i use otter box).

Smart phones better than iPhone 5 with ios 7?

I wanted an HTC One but my mom said I couldn't get another phone until she got her new iPhone this fall. Should I just get an iPhone too or will there be anything better to go for? As long as it doesn't frustrate me too much with lack of capability, it'll work. I haven't really considered price but I just wanted to know what the fastest phone with camera and best sound quality is.

Added (1). I have at&t. I have an htc inspire right now and it has so many abnormal resets, freezes, and it no longer views message-received photos as of a year and a half ago.

Helping around the house

Ok so If I read my summer reading book I can get the iPhone 5 and that's not what I'm worrying about because I need to read 12 pages a day to get to my goal to be done the book in 24 days. I already read 36 pages today so I no I will be done in time!

But now I want the lifeproof case which is like $90. My mom said I can get it if I start helping out around the house!

What are some ways to clean or what to do that is easy but makes a huge difference. Like I put away the dishes sometimes but I need to do more in a day! So what are more ways to help out my mom around the house!
