Instagram not letting me access my own profile?

So I have an instagram which I access mostly through an app on my iphone 4. Usually everything is all fine and dandy, but recently I've encountered some problems. My account is set on private, and now whenever I try to click on my profile, it won't let me look at my own pictures… It says I'm on private… I have tried everything. Reset my phone multiple times, deleted the app and reinstalled, changed my password, logged out, logged in… And I also am unable to upload photos! It's really frustrating because I really like instagram and I like to use it but it's not working so if you can help me please help!

Does the iPhone 5 have a warranty?

I got my iPhone 5 in late January and a few days ago my volume down button stopped working. I have the monthly instance thing with Verizon but I don't really want to file an insurance claim just for a button. Like I can live without it working but it's just annoying.

Data plan being used even when connected to Wi-Fi?

Ok I have an iPhone 5 with a 200 GB data plan. I don't understand how I'm going over my plan even when I'm connected to a Wi-Fi network, have cellular data off, close All apps in the back ground, and have current locations off. I switched from a blackberry torch 9800 and never had this problem. What should I do?

IPhone 5 keeps disconnecting from my home Wi-Fi?

Okay, so my iPhone always randomly disconnects itself from my home Internet. It's not the phone because this also happened on my previous iPhone. I've closed all recent apps, restarted the phone, restarted the Internet, disconnected then reconnected to the Internet, I've renewed the lease, I've turned aeroplane mode on and off, I've turned the Wi-Fi option on and off, I've done everything. I'm thinking it has something to do with the battery usage, because it happens most when my battery is around 30% or under. If so, how would I change this so it stops automatically disconnecting?

Any help would be much appreciated.
