I'm rough on phones and when you put phones in your purse you tend to get scratches from, keys, pens, etc. Just one case won't work for me, as I like to change them to match stuff (yes, I'm female) LOL LOL
I have found some nice, colorful protection cases such as these and I have found some great deals on Ebay and Amazon.com. Because I change so much, that I keep the phone clean and such. I also have one of those plastic screen guards on the phne that works great!
