Possible to switch iphone iOS 7 icons?

Can I change iOS app icons in ios 7 using this method: http://www.iphonefaq.org/archives/971085?
I haven't updated yet because In my opinion the icons in 7 look like they were scraped off the floor of a first grade art class… All that's missing is the glitter and macaroni. Yes that is the only reason I'm not switching. Maybe I'm being picky, but I don't care don't try to sell me on them. All I want to know is if its possible to get rid of them once I have the update

AGREED. The website you cited seems legit, the update might not be worth getting if you don't like the whole color scheme. That's basically the only change, everything looks different. The only real difference is if you actually buy the new phone.
