Instagram problems on IPhone 4?

I had Instagram on my IPhone and it was freezing up a ton so I finally ended up deleting it so I could just reinstall it or whatever. So I went back to the AppStore and I hit install and it said it was installing for literally 2 seconds and it just stopped. Now I can't get my Instagram back. And I'm EXTREMELY frustrated. Does anyone know what's going on with my device? And does anyone know how I can get my Instagram back?

How to sell $100 best buy gift card that I desperately don't want?

I have a best buy gift card worth $100. I do not want it since the company screwed me over bad. I had an iPhone that was stolen in a robbery. Best buy in store told me I couldn't get a refund for my geek squad plan. They said call 1800 number. I did this for 6 months. Finally the store refunded it but only the prorated and on a gift card. I would rather be castrated than give them another penny of my money. The problem is my family isn't a tech family and prefer wal mart. How can I sell this and wipe my hands clean?

Added (1). Can't sell them their own card

Added (1). Stupidly I forgot to list what I've already tried, I've tried resetting the settings, updating the phone, resetting through iTunes, hard resetting phone and turning off for a period of time nothing has fixed the issue if my Internet was affected too I'd take for granted that the phone had already broken its annoying since I've had the phone such a short time
