How to post pictures on Instagram from iPhone when the top part of your screen doesn't work?

So sometime over the summer, the top part of my screen became unresponsive on my iPhone and I can't replace my screen at the moment… And I'm like a HUGE Instagram-er and I'm missing it like crazy! And I was uploading pictures using my tablet but I don't have that anymore and I need a way to upload pictures and I was wondering if there was a way that I could post using my iPhone with it's messed up screen? Anything that could help me out?!

IPhone 5 isn't receiving Texts well after Battery Died?

Had some weird issues. IPhone 5 battery ran down and after it died the charger stopped working.

Working on another charger and all is fine as far as power is concerned. However, people can't text me normally. To them, it auto-failed the iMessage and sends as a text message and I'm not receiving the majority of the messages they send.

What would you suggest I do to fix this?

Router gives PC Internet, but none of the other devices?

I have a Belkin n300 Wi-Fi router. My PC has Internet access, but whenever I try to access it on another device (such as my iPhone), my network shows up but will not connect. I'll type in my password, but all it does is buffer. It also won't connect to my Xbox.

Is there a way to fix this?
