Help fixing the front screen of an iPhone 4s?

I just dropped my iphone 4s and cracked the entire front screen. The LED or actual screen isn't defected and the touch screen works perfectly. The only problem is the broken glass. Do you guys recommend buying my own new glass screen and installing on my own, or should I take it to a repair place and let them handle it? Please tell me what I should do and how much time and money it will take (aprox.)!

Should i trade in my iphone 4s for an iphone 5 or wait?

I have no problems with my iphone 4s really. But I'm due for a free upgrade already and Best Buy is having that trade in offer. I know it's giving them a free 100 dollars because my phone is currently worth like 300. But I don't know how to sell it/use craigslist or ebay so I really don't care. Please don't criticize me haha I really don't see how it's a bad idea because I don't mind a 2 year contract again. Should I wait for the iphone 5s or 6 though? My mom wants to leave now to take me there and I need quick opinions please and thank you!

Best running application for iPhone 5?

I had recently used runkeeper. But now the GPS just sucks, other people from what I have read have the same problem as well. Went for a short 2 mile run with a 2 mile walk back. The 2 mile run registered correctly, and the 2 mile walk back registered as 1.25 miles.

So any good apps for running? I don't care if they cost money either.

Thank you

Added (1). It's not my phone, i know that for sure. I had read online that others were experiencing the same problems as I for this app.

Any programs/apps that let you change the hair color in a picture?

Aside from Photoshop, since that is something I've yet to tackle.

Basically, I have this friend who wants a new hairstyle. She's really outgoing and she has this wacky, bold style. She wears bright colors, layers upon layers of jewelry on top of each other, mismatched socks and shoes and gloves and patterns, etc. But her hair is dull. It's long and plain brown. She says that she wants to change it, but that nothing works for her. Which is understandable, since she has a very round, ovular face, which can be difficult to pick a suitable hairstyle for.

Well, I have a haircut picked out, more or less, but I'm stuck on the color. I think she would look good (and mature enough to contrast her slight baby face) if her hair was blonde. I've asked others if blonde would fit, and they've all said yes, but it would be a huge change from dark brown. I'd rather be able to have some picture to give her when I recommend the color, so that she's more open-minded and sure of the idea.

Are there any programs online where I could upload a picture of her and play with the colors in her hair? Or an iPhone app?
