Why won't my iphone 4s connect to Wi-Fi? - 2

For the past few weeks, i can't connect to my Wi-Fi or friends Wi-Fi.

I've tried resetting the phone, I've also tried resetting the network settings too and this still doesn't help. I've tried everything that I've looked up on and nothing seems to help.

Also i can't use my 3G to do anything in a house where i was connected to Wi-Fi, or send texts.

At home i try and send texts and it doesn't work, then i try and use my 3G for apps but that doesn't work either, only when i'm outside the house.

I really need help! Any suggestions will be very much appreciated.

Can you use a lost or stolen Iphone 5s Tmobile?

I have an iphone 5s and I have insurance that covers lost, stolen or damaged. So I was wondering is if I lose my phone I get a new one. But can someone use my old one?

When I set up the phone the first time. Tmobile needed the IMEI number and a different number. I think the serial.

I just wanted to know if they block lost or stolen phones. Cause to be honest I wanted to give one to my sister and I know previously you could do this and save a lot of money.

My Instagram app keeps crashing?

I have an iPhone 4S with iOS 7 installed. I've had Instagram for a long time and have uploaded over 300 photos, and have never had a problem until now. When I try to upload a picture, it takes me through the cropping and editing screens, and then as soon as it gets to the "add a caption" part, it freezes for a second and then closes the app. This is super frustrating and I've even tried logging into my account on a friends phone to upload a photo, and it still crashes, even though my friend never has this problem on her account.

No texts received, but this number keeps showing up in my messages?

I don't know how to describe this. About once a week I'll open my messages (on an iphone if that matters) and this number I don't know will be at the top of my inbox… It's in my area code so I don't think it's spam, but what confuses me is that I DON't GET ANYTHING… I have no messages from them, the number just jumps to the top of my list with nothing there at all…

Does anyone know what's happening? I mean it's easy enough to ignore it, it just really weirds me out

Where do my notes from my iPhone go?

My notes on my iPhone keep disappearing. A day after I write a note, they disappear. When I go to iCloud, they are not there. I can't find them on Outlook or Yahoo. Yahoo mail is my default account according to the notes setting on my iPhone. But I can't find them. Any idea where they are going to?
