Is is hard to replace iphone 4 screen?

I cracked the front of my iphone 4 screen. I called Verizon and it costs to much to have fixed/replaced so i thought i could buy the kit off amazon with like a cool blue screen or something. I looked on ebay to see how difficult it would be to do and it seems really hard! There are some steps i could do but i don't trust myself.
Is it as hard as it looks? And If i do it right will the picture and camera still be the same (quality etc)

It isn't as hard as it looks. My boyfriend broke his iPad screen and ordered a kit off Ebay to fix it. The Kit and the YouTube videos made changing the screen fool's proof. He is far from computer savvy and his iPad looks good as new. Everything functions the same. Just get a screen protector and a case next time. Best of luck with repairing your phone.

Take it and ask peope at a cellphone place

Not really

If you don't have any technical skills about repairing cellphone, it may be not easy.

I have an iphone 4 that i bought with the screen cracked for 130$ i bought a screen from ebay for 21$ and replaced myself it took me about 4 hours to place everything exactly how it was but it was my first time and my iphone is still working if you have nerves to do it your good.
