IPhone won't connect to cellular data network?

My iPhone will not connect to cellular data network at all. It was just working a few hours ago but suddenly it won't. I've tried restarting it twice. I've tried turning on and off airplane mode waiting 5 seconds in between. And turned off and on cellular data. I've reset the network settings too but nothing is working. What can I do? I'd rather not have to restore iPhone as new. I have an iPhone 4S and I don't have iOS7 because I never had enough space to download it. Any suggestions?

My battery life (iPhone 5) (iOS7)?

So, i don't know why but my standby time and usage time are the same and that just doesn't make any sense it's just impossible. I don't know how to fix that. Please help me! I've already tried killing my apps running in the background, rebooting even resetting my iPhone and setting it up as a new phone!

How to sell an iphone, or put it towards a Dell?

I'm trying to either convert my old iphone 4 into cash to put towards a Dell laptop, or trade it in at a store that can give me a percentage off of my purchase of the laptop. It's a Verizon phone by the way, with no contract. Does anyone have any suggestions? I would highly prefer to do this in person, even if that means putting it on Craigslist (which is my last resort).

Why don't cons realize everything they believe is wrong because of slavery?

Conservatives believe that we should keep the ideas of the past cause they think those ideas made America rich or something. What they don't understand is that cause we had slavery that means all old ideas are bad. Besides people today are so much smarter than old time people. Ben Franklin didn't even know how to use an iphone.

So, all new ideas are automatically good. Hopefully we can get a liberal government like North Korea where the government owns everything and we work for free for the government instead of slavery like the cons want.

Is 16gb enough for the iphone 5s?

I'm planning on purchasing an apple iPhone 5S today because my 2-year contract ended and I can get the phone for the price of it with a 2-year contract. Though I'm still wondering which amount of storage space to get. I never download music on my devices, because I figure i can just download pandora or any other music streaming app for that. And I don't take pictures on my devices, though I do occasionally download a picture off of the internet. But I do like to have apps. On my iPad which i've had for 6 months now i have downloaded 30 apps.So, in your opinion, which amount of space should i get, 16 gigabytes, or 32 gigabytes. Money wise I would like to not have to spend the extra $100.

What is the best/cheap thing to do with a water damaged iPhone 5?

I dropped my iPhone 5 in a bucket of water. It still works but the screen flickers on and off. Sometimes going off for days and then coming back again.

How do I fix/where do I send it too and how much will it cost me?

FYI I've been to Apple and don't have £200 odd to replace it and it's not insured, stupid I know but that's my own fault.

Added (1). Thanks for that but what if my contract is not up?

Does GPS iphone 4s use data?

I started using maps app in my iphone 4s while driving. I have limited data package and so concerned about the data being used while gps is enable. I got impression that it only use data when i search the location and then it use the built-in GPS while moving. I doubt it may use data all the time.

I would appreciate if you could recommend the solution.
